I currently have:
- Antec Earthwatts 500W PSU
- 3750K CPU
- ASRock H77M motherboard
- Radeon 7870 Tahiti LE GPU
I'm tempted to get a second 7870 Tahiti LE.
I know I'll need to upgrade my PSU (to 650W+ as I have many HDDs, plus one that supports CFX).
So, provided my PSU is ready, should I get a second 7870 Tahihi LE?
Have AMD fixed their CFX problems? (I heard something aobut unstable frames due to syncing or something?)
I've seen in some general CFX benchmarks that some games etc. utlise 100% of the second card. Does that mean, as long as the CPU is capable, that the framerates will double that of a single card?
Talking of a capable CPU, would my 3750K suffice?
Finally, my motherboard only supports 1x x16. The other slot is an x4, which means I believe both cards would run at x4. Would this be a huge issue? Would I need a new motherboard that supports 2x x8 (or 2x x16) to make 2x 7870 Tahiti LE worth it?
