Yes, I meant the 780. I may have the ability to get a computer during Summer. Of course, I could always wait for the release for the release of GDDR6 VRAM. Is the improvement very significant?
Also, Intel Haswell question. I would love the i5 4670K. However, there are no motherboards yet supporting the LGA1150 socket. Will these motherboards be expensive ($150+), or still be in the average range ($100-$140)?
The new platform will likely have a premium, not to mention Haswell itself isn't a huge improvement over Ivy Bridge, or even Sandy Bridge (being Ivy was in incremental update over Sandy), strictly speaking for the CPU. The iGPU is an entirely different matter. It seems that Intel figures it has a huge upper-hand in CPU speed, so it's diverting R&D resources to iGPU and power consumption to compete with AMD's APU's and in the mobile space. Any 2nd gen or greater Core i5 or I7 is more than enough for gaming. I still can't find a game that my 2500k is more than enough for, granted it's OC'd to 4.5GHz.
As for the GPU, don't play the waiting game - you'll be waiting forever. GDDR5 is enough, and there aren't any memory bandwidth bottlenecks until you really step up the resolution. The GTX 700 series is a Kepler refresh, though the 780 will be based on the GK110 (same GPU the Titan is based on), so that might be worth waiting for, esecially considering the price drop.
Protip: If you're going to wait, don't linger too long. Just get what's going to come first.
