XFX 280x 3gb vs Gainward gtx 770 phantom 2gb
Hi guys, i am finally ready to buy my new build. Its a matter of 2 days before i go to the shop. But at the last moment the shop im using got new GPUs with nice prices. Originally i was going for XFX R9 280x, Now they received Gainward GTX 770 phantom 2gb,
Now, Im playing mostly World of Warcraft, the rest of my games are: Diablo 3, Assassin's Creed, Splinter Cell, Hitman: Absolution and i wanna try the new Thief. There are more Nvidia titles then AMD in my list, Wow clearly prefers nvidia, if you google wow r9 280x the first things that come are tesselation and artifacting problems. However, as much as i like gtx 770 option, i am not familiar with Gainward. Is it's cooling good? I have an everlasting cooling problem, my room is really hot. Also please consider that r9 280x is 3gb. Which one do i choose?
I am not overoclocking, not gonna do sli/crossfire ever, im using my gpu as is, no modifications. My CPU will be i5 4670. Other components will be adjusted to these 2.
Thanks in advance
