My father is looking to upgrade my sibling's PCs to GTX 660s, I happen to own one and he is willing to buy it at full price ($120-150) as it is on Newegg. I need some helpful insight though...
Lets assume +$50 for the 4GB version and similar improvement as the 760 2GB vs 4GB.
In short for the moment:
$200 for the 2GB 960 $80- $60
*$260* for the 4GB 960 $140- $110 \____$90 diff.
$330 for the 3.5GB 970 $210- $180 /
^That lack of lists
+33% performance from a quick comparison of 960 2GB vs 970
Is 33% performance worth 300% more effective expense?
So far it seems like the winner to me is the 960 2GB with the effective cost of $60 vs 3 times that but now we get to the stuff I will be combining it with:
ASUS p5K PRO (1x16 PCI-E 1.0) No SLI
8GB DDR2
600W PSU
Q6600
2TB WD Caviar Green Drive
CPU aside, can the GTX 960(assume 2, then predict 4GB) run Skyrim with ENBs at 60+ fps?
