Hello. I'm going to be building a rig with all top parts and the only trouble I'm having is with choosing a GPU. The 690 and Titan are overpriced. I would like to get one though, although I can't seem to find one. If not that I would like specifically looking for the top of the line GTX-680 (I believe it's the Classified model) or the top 7970 GHz edition. No arguments, just straight answers please! If anyone knows where and I can find them in stock. I read that Titan's are out of stock all across the web and it seems the same for the 690. Would it be better if I went with the 680 or 7970 GHz or got a Titan. I play a lot of FPS and other mild-moderate gaming as well as other moderate graphics consuming tasks. Would it be worth the Titan or 690? Would it be worth it to get the top of the line 680 or top 7970 GHz? Anything that just may be as good if not better? I've done lots of research on all of this, repair computers for a living, just having a hard choice here and in need of some enlightment. I plan not to upgrade this system for around 2-4 years after I get it. But I don't even think I'm going to do that considering I'm getting 32 GB of 1600 MHz RAM. My CPU is going to be an i7-3770k if that helps just incase these cards will bottleneck (which will probably not considering this is one of the gamers CPU of choice, and the best one out there). Thanks for your time, and have a great day! Also I will be running a single-monitor setup. Possibly HDMI, possibly DVI. Not sure yet.
