Since I haven't upgraded my GPU since September '09 (ATI Radeon HD5870) I think its about time. This card has been dope for a long time but I'm finally starting to see slowdown in some games (Arkham City comes to mind).
Pretty much thinking the GTX 680. I have no problems paying $520 for a card that will last me 3+ years, just wondering if I will run into any bottlenecks with my current setup:
AMD Phenom II x6 1090T OC'd @ 4.0GHz
16 GB G-skill DDR3 @ 1333 MHz
4x Mushkin 60GB SATA3 SSD in RAID0 (2GB r/w)
ASUS Sabertooth 990FX
Black Widow 850 watt PSU
I have a Phenom 980 @ 4.2 Ghz and you will not bottleneck at all unless the game is cpu intensive such as Bf3 on large maps 32-64 players.
Other than that, there shouldn't be a problem.
