Some of you might remember that last summer I built myself a fancy little gaming pc. Here are some specs; Intel i5 4670k cpu w/ Cooler Master 212 Evo cooler EVGA GTX 650 Ti Boost Superclocked edition (2gb) gpu Asus Maximus VI Hero motherboard EVGA Supernova 1000 G2 power supply Acer 24in. 60hz 1080p monitor Blah blah 1tb hdd, blah blah cd burner. Whatever. Anyways, I'm looking to get a new GPU, as the 650 is really starting to make its limitations apparent, and it just bugs me to not be able to max out all my games if we're being totally honest. I've thought about sli'ing it, but decided against it and just getting a better single core and upgrading that to sli much much later. Where my dilemma arises is choosing a new video card. I really want to get a GTX 780, but I also keep hearing great things about the R9 290. Any pc gamers out there running either of these? Frankly I know this is overkill atm, especially since I don't plan on upgrading my monitor or anything, but just the knowledge of future proofing my pc for at least a couple years would be nice.
