I am in the market for a new graphics, I was having trouble deciding between the HIS ice q 7870 and HIS ice q 7950, i was wondering if its worth the extra $70 for the 7950, I am running an AMD phenom II X6 1045t, I want to get the most for my money and some longevity out of the card. I am hoping to run games like BF3 at close to ultra, skyrim, Borderland 2 with high physx, and such, my monitor resolution is 1920x1200.
Unless you plan to play at higher than 1080p there is no need for more than 2GB
The 7950 cannot really use up the 3gb before its too slow but the 3gb will be useful for future crossfire/multi-screen (as you basically need crossfire or the top end cards (7970/680/670) to play well on multi screens at decent settings)
Most cards with the stock cooler will vent all air out and be fine while ones with aftermarket coolers will cool adequately even in poorly ventilated cases
The extra bandwidth is not needed as the gpu craps out before all the memory bandwidth is needed for AMD cards (unlike nvidias cards as you can see they drop off dramatically as more AA [which requries mroe bandwidth] is applied
To quote: It’s plain to see that the smaller memory interface doesn’t really impact performance.
^ a good cpu like the i5 3570k or i7 3770k or FX8350 should be able to tank phsyx
I regret to say I missed the PhysX part in the original post

An decent cpu should let you have PhysX on low/medium without issue
keep in mind this review is before the massive performance enhancing 12.11 drivers from AMD
also the cpu is a 3960x
The 680 with Physx on high performs the same as the 7970 with PhysX high
And here is CPU vs GPU handling the PhysX (the 580 has about same phsyX perf as the 660ti
You will likely suffer memory bottleneck issues though if you're actually using 2+gb of VRAM on the 660ti's 192bit mem bus
In order to get rid of them you will need to bump to 670 and spend extra $120 over the 660ti and even the 670 will take a hit
You can see a sharp dive in Nvidia cards as 4x MSAA is applied, and the difference between the 660 and 660ti narrow a lot even at 2xMSAA due to memory bottleneck issues
