Will This Bottleneck My System


Recommended Posts

I have a system running on a Phenom II X4 965 BE proc with 4 gb ram, Radeon HD 6870 running on a 650 watt power supply. I'm thinking of buying a second one so I can run cross-fire but will I be bottle-necking my system by doing that or no? And should my power supply be good enough or would I need something stronger?

you'd be cutting it fairly close with that power supply,

600 watt is the minimum recommended psu for cross-fire with the 6870 but that doesn't take into account for other things plugged in as well

so I'd recommend upgrading PSU then you'd be fine

What is the model of PSU. 650w should be fine if it's a decent one. I'd consider getting a new mobo and an intel CPU if I was you. Your 6870 shouldn't be having trouble with much right now? Having said that two 6870's should chomp anything you throw at them for a year or two.

Do you have a SSD yet? Consider that also if you don't.

The model of my PSU is here http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005 In January of 2013 the computer will be 2 years old because thats when I built it. I didnt have the money back then for an intel build so thats why I went with an amd build. Also, no I don't have an SSD yet but have heard the increase in performance is so much better. Can you recommend a good one for cheap?

    • Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know The ONLY thing I need to know is the price, which I know will be way higher than I (and most people) are willing to pay for a phone... so basically nothing here I need to know. PS: Nice job getting that Apple reference to a non-existent and unrevealed product as "competition" in there. Cheque is in the mail.
    • Well I really think the repasting helped if your higher clocks have returned, maybe the next thing to look at is if there is a problem with your case airflow? I guess this because your 3080 has returned to optimal state, but is still staying too warm, which might suggest it was thermal throttling before you repasted, of which the only logical conclusion could be outside factors.
    • Samsung Galaxy Z Fold 8, Flip 8, Z Fold Wide: Everything you need to know by Hamid Ganji Galaxy Z Fold 7 - Image via Samsung The next generation of Samsung foldables is set to be unveiled next month at the second Unpacked event of the year. Samsung’s 2026 foldables are not expected to offer significant upgrades over their predecessors, with the Korean firm instead focusing on design refinements and conventional upgrades such as faster processors and better cameras. However, Samsung is reportedly planning to unveil an all-new passport-style foldable this year to rival Apple’s first foldable iPhone, which is expected to debut this September. Here’s a roundup of everything we know about Samsung’s upcoming foldable devices ahead of their official debut. When can we expect Samsung’s new foldables? The Galaxy Z Fold 7 and Z Flip 7 series were unveiled in July, and Samsung is expected to maintain this timeframe in 2026. Based on previous reports from Korean sources, Samsung will hold its Unpacked event on July 22 in London, UK, to pull back the curtain on the Galaxy Z Fold 8 series. The devices are also expected to hit the shelves a few weeks after launch. However, Samsung has yet to announce an official date. A new naming scheme? One of the most interesting changes we might see this year is a new naming scheme for Samsung’s latest foldables. SamMobile reported that since Samsung is expected to unveil three foldables this year, it has adopted a new naming strategy to simplify product identification for customers. Accordingly, the standard Galaxy Z Fold 8 will reportedly be called the Galaxy Z Fold 8 Ultra and will serve as the direct successor to last year’s Galaxy Z Fold 7. The “Ultra” suffix suggests the phone could feature higher-end specifications, such as additional rear camera modules. Samsung’s new passport-style foldable is expected to carry the Galaxy Z Fold 8 name without any suffix. This model is reportedly equipped with two rear cameras. No major changes are expected for the Flip model. Galaxy Z Fold 8 Ultra and Z Flip 8 anticipated specs Rumors over the past few months suggest Samsung is preparing several upgrades for its upcoming foldables, although the devices may continue to rely on larger batteries and faster charging speeds rather than dramatic design changes. The primary focus this year is expected to be the Galaxy Z Fold 8 and its wide-screen design.

Expected specifications include: Snapdragon 8 Elite Gen 5 or Exynos 2600 processor 12GB of RAM with 256GB and 512GB storage options 6.9-inch Dynamic AMOLED 2X inner dispaly and 4.1-inch Super AMOLED outer dispaly 50MP main camera, 12MP ultrawide camera, and 10MP selfie camera 4,300mAh battery with 25W wired charging Android 17 and One UI 9 Samsung’s foldables are also expected to launch with Gemini Intelligence, Google’s AI suite for automating tasks in Android ecosystem. Moreover, given current memory and component costs, some Galaxy Z Fold 8 Ultra and Z Flip 8 variants could see a price hike. Galaxy Z Fold 8 adopts a wide-screen design The centerpiece of the upcoming Unpacked event could be the Galaxy Z Fold 8, previously rumored as the Galaxy Z Fold Wide. This model adopts a passport-style form factor and is expected to compete directly with Apple’s iPhone Fold. Galaxy Z Fold 8 official CAD renders - Image via AndroidHeadlines Here’s what to expect: 7.6-inch primary OLED display and 5.4-inch cover display, 120Hz refresh rate, 2,600 nits peak brightness, and 4:3 aspect ratio Snapdragon 8 Elite Gen 5 processor, 12GB or 16GB of RAM, and 256GB, 512GB, or 1TB storage options 4,800mAh battery with 45W wired charging 50MP main camera, 50MP ultrawide camera, and 10MP selfie camera Android 17 and One UI 9 The three new foldable phones are unlikely to be the only devices unveiled at Samsung’s Unpacked event. The company is also expected to introduce the Galaxy Watch Ultra 2 and the Galaxy Watch 9 series.
