[Killingfloorcombat]

Ok so I need help finding a video card
In the future I will be adding a second
Card (same as the one I'm getting for starters)
My rig right now is :
CPU-amd fx 8120 bulldozer 3.1 ghz x8 (going to over clock)
Mobo-asus crosshairs v formula 990fx r.o.g
Ram- 8gb corsair vengeance 1600 ddr3
Psu- rosewill 650w modular (can upgrade if needed to)
Hdd- seagate 1.5tb 7200rpm x2 (2x1.5tb) (storage only have ssd for op. Sys.)
Opd-lite on DVD/cd rewritable/player
Case- custom acrylic
But so far I've kinda been leaning twords a
Asus gtx560 (non-ti) dcii 1gb or the msi twin frozrii hd 6870 1gb
My budget for the card is $200 please any input is helpful!!

Newegg.com - GIGABYTE GV-R687OC-1GD Radeon HD 6870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card with Eyefinity

Best card for your budget. You have 1 dollar left

With all seriousness though, the GTX560 TI competes with the hd6870, so I'd assume the GTX 560 will be a little less performant
