I'm currently running an original Core 2 Quad Core CPU with a GTX 470. This PC was built 7 years ago, still runs nice but games are starting to struggle mostly because of the CPU, but the older 470 isn't helping. I've put a new build together, but I can't decide if I should get a GTX 770 (the ASUS model is currently $299 with Free Copy of Watch Dogs), the GTX 780 (priced at $509 w/ Watch Dogs included like the other), or wait for the new 800 series. Realistically, the 800 series will probably be priced at the original 700 series levels, so I'd probably be spending an extra $100 or so on an gtx 870. Whatever I end up doing will be an upgrade. I'd like to play at max settings and I will be on 1920 x 1080 with a single monitor, so nothing crazy. I also thought about getting the 770 and just waiting for it to drop in price and get a 2nd for SLI, though with a single monitor at that resolution, I don't think I'd really be reaping the benefits.
