help???!!!!!
what to do???
Yes. There isn't too much between them at stock, but the 7870 has better OC headroom- and more to the point, there are a good selection of factory pre-overclocked cards to be had- Just keep an eye on the prices, since some of the factory special 7870's are approaching the price of a 7950.7870 stronger than 570gtx??
Did you not read the post above?
A 7850 or GTX 570 are good suggestions, anything higher and your CPU might start to bottleneck the system.
Since you have $600-700 to spend, I'd put $100 towards a decent PSU (avoid OCZ though unless it's the ZX series), e.g. the Corsair TX650v2 or a Seasonic X650 if you want a quality modular PSU. You should then save up a bit more and think about upgrading that CPU to a quad core Sandy Bridge/Ivy Bridge.
The ModXStream failed [H]'s review, their lower end PSUs have been shown to use poor quality components. Plus OCZ as a company are renowned for poor customer service, questionable business practices and buggy SSD firmware.Is there a reason to avoid OCZ PSU's? I bought one several years ago and never had any problems so far.
I was thinking if your going to try to put a gr8 gfx card you should first try putting atleast an i5 2500k 200$ which wont bottleneck the gfx cardI3-540, 3066MHZ
