Hi all, Following on from my recent HD7850 1GB Eyefinity "review" I now have an urge to play on my Eyefinity setup properly again. Yes I tried Crysis 3 and the poor 7850 waved a little white flag. Now obviously this will require a much more powerful card than the HD7850 and thus I am looking into either the option of a R9 290 or simply get another GTX780 (already owned two in the past & benched Surround extensivly). Both of these cards should offer up more than playable framerates in the games I want to play (based on my own previous testing) thus in outright performance terms they are basically interchangable. There is only one small problem though, the system was bult as a budget gaming system for my wife and thus includes a Athlon II X4 760K.... (A great budget CPU btw) Now normally I would laugh at the prospect at partnering a GTX780 / 290 with a weak CPU (in comparison to a i7), but given I will be running a resolution of 5888x1080 will it be such a problem? (For a useless comparison a heavily overclocked HD7850 (1200/5400) was constantly pegged at 99% GPU usage). I remember overclocking my old 2500K / 3770K made no difference to FPS in the games I was playing at the time (I don't play RTS games) in Surrond / Eyefinity, so theorectically I should be able to get away with a slower CPU (I know a 760K is slower than a stock 2500K). I will be overclocking the 760K as far as possible when gaming to help aleviate any potential bottleneck. I don't have the budget to replace everything (CPU / MB)* so I have two potential possibilities: 1) Get a 290 / GTX780 and hope there is little or no bottlenecking; 2) Get a cheaper 280X / GTX770 and put up with lower than preferred performance (based on the known outright performance of both GPU's). Option one gives the potential for more performance but option 2 might be the safer bet - although has a maximum performance ceiling which I already aware of (had numerous HD7970's / GTX680's). Anyway enough waffle (I could go on and on about Eyefnity / Surround performance potential but I won't), what do you guys think about the potential bottleneck here? Potentially massive or not enough to worry about given the resolution requirements & subsequent GPU bottleneck? *Well TBH considering I havn't even mentioned this to my wife, I doubt I will have the budget for anything but hey. Apparantly a new Kitchen is more important than higher framerates... WTF?!
