Hi, I just bought Bioshock infinite today but my computer cannot handle it, lags real hard during fighting sequences, and shuts down randomly, so I am looking to get a new graphics card.
I am currently using Geforce 550ti, i5 2500k @3.3ghz cpu, my motherboard is
GIGABYTE GA-P67A-UD3-B3: it says it support for ATI CrossFireX.
My budget for new video card is around 300 USD , so I narrowed it down to these two after following tom's hardware best bang for the buck gfx card guide.
XFX Radeon HD 7950 vs SAPPHIRE Radeon HD 7950;
They are the same price on newegg, but I don't know if they are necessarily the same, one has Boost Clock with lower core clock, and I am not familiar with overclocking things.
Btw, should I get newer graphics card opposed to these that had been released for a while?
Thanks for the help in advance!
