Go with the 780 or 780 Ti. Single card performance is always better and 2 770's will cost more than a 780 Ti.
yada yada I would recommend AMD cards for those prices yada yada
That aside, wtf you're wrong. Single card performance is not always better. 2 770s will cost more than a single 780 Ti, but they'll perform significantly better, with a much better price/performance ratio. If he were to only go with only a single card, it should be a 6gb version of the 780 and not the ti, because the ti only has 3gb of vram, which isn't good at all for 4k resolution and if he wants to SLI in the future he'll have to completely rebuy. If he's buying bisjac's cards, I would definiteky recommend them because I know he has 4gb variants of the 770s
i heard choosemypc.net is better than Logical Increments? can anyone confirm/deny?
Seems like the $1000 build is better than the one on logicalincrements. Didn't check any of the others, but probably it's better in general. The problem with all of these "give me a budget and I'll give you a build" sites though, is that you're losing your ability to pick components. When people ask other people for a build, they're not entirely sure about just one decision so they go to multiple people for multiple opinions, which is good. But, when it's a nice-looking site, people just buy it without consulting anyone else. It looks like a good tool for a starting point, and then you can customize your build from there
I think the CPU and GPU choices are decent, I really dislike how much it skimps on the motherboard though. I've bought ASRock motherboards before (It tends to recommend them), and they tended to die rather fast.
Jeez, why does everyone here not like ASRock. I've used several ASRock motherboards, and none of them have died. Obviously that proves nothing, but they are indeed a budget motherboard builder. The fact of the matter is, if you want a motherboard on the cheap from a reputable brand, ASRock is pretty much the only choice. There are better motherboards, but they cost more. ASRock boards do what they're supposed to do, for the price they're supposed to do it for.
