Need GPU & FPS Advice

[moreinput]

I'm currently looking to increase my fps as I'm only getting around 21fps with ultra settings on games like Rift and will be playing Guild Wars 2 very shortly. Nothing less then ultra settings. I would love to see it more towards 40fps. I will be building a new pc more towards the fall and might go with Intel and SLi, but perhaps a new GPU to hold me over until then. My computer is very fast and handles everything smoothly so I have no complaints anywhere else.

Currently

-AMD Phenom II x4 970 AM3 3.5GHz

-ASUS M4A78LT-M AM3 AMD 760G Micro ATX

-G.SKILL Ripjaws Series 8GB (2 x 4GB) DDR3 1066(PC3 8500)

-XFX Radeon HD 5770 1GB DDR5 PCI Express 2.0

Hanns-G HZ281HPB 27.5" 3ms 1920x1200

Enermax Liberty 500W

ZALMAN CNPS9500A-LED 92mm CPU Cooler

Corsair Force Series GT CSSD-F120GBGT-BK 120GB SATA III(6GB/s) SSD

Windows 7 Ultimate 64-bit

I could purchase a new GPU with PCI Express 3.0 as its backwards compatible and I can then toss it into my new system when I get it built after the summer. I do want to try an Intel build though. Any advice on a new GPU? I was looking to spend up to $400 on one although I might not be able to take full advantage with only a pci express 2.0 mobo. I would imagine it would greatly out perform my current one though. Any advice would be greatly appreciated.

Cheers

Since you seem to like AMD and XFX, I recommend the XFX AMD Radeon HD7850 2gb http://www.newegg.com/Product/Product.aspx?Item=N82E16814150609

Also, your power supply is on the weak end, so i would recommend at least a 750W power supply upgrade as well. http://www.newegg.com/Product/Product.aspx?Item=N82E16817703027

Thanks for the input. I like the recommendation and will soon get these two items. Hoping I can push 30fps. Thanks again!

I guess I will have to purchase an intel board/cpu in the future as AMD has no mobos with PCI express 3.0. Will I be able to SLi two of these video cards mentioned above?

PCI-e is backwards compatible, you do not need a PCI-e 3.0 mb to use a PCI-e 3.0 card, and you won't suffer any real world performance loss without one (most video cards still don't come close to saturating PCI-e bandwidth).

While intel cpu's are definitely better right now, most games are not cpu bottlenecked. The rest of your PC is still fine for games, I see no need to upgrade anything but the video card right now imo. A video card upgrade should certainly get you 30+ fps in games.
