gtx 460 ftw by evga is best under 200$,it outperforms hd 6850/6870.
The EVGA FTW card is usually about $230, not under $200. Paying for a factory overclock when there are significantly cheaper cards with better cooling that you can easily overclock yourself doesn't make much sense IMO.
I have the EVGA 1371TR - OC 720 - 1gb. I've added 10% to 792 without gaining one degree of heat. It idles in my case(35c) at 31c, maxes to 41c. It blazes thru MSFX and Race07 like a hot knife thru butter.
i terms of quality i'd say #1 asus, number 2 msi, number 3 gigabyte and evg are just overclocked refrence cards.. but they are very user friendly and a well run company so should you have an issue they will be quick to help you out.
i agree the gtx 460 for your res is probably the best dicition it'll run wow in ultra at your res withought breaking a sweat, no need to get the ftw as its the same as the free performane boost gtx 460 (ie both refrence) if you are gonna spend more either of the other brands i mentioned you won't go wrong with
forgot to mention... 2 gigs in a gtx 460 is useless here's a review
