If you're getting the money in 3 months i'll say wait for another 3 months after that for maxwell. Gtx 780ti is really not worth it, especially with only 3gb of vram for 700 bucks. Maxwell should have at least 4gb of vram so better to wait for that. I have a really old ass graphic card too that im still using for almost 5 years, the gtx 260. I'll also be waiting for maxwell unless the non ref r9 290x is really good.
