Oh, that is all they cost? I think I have a spare lung here somewhere...
I place the TI cards in the "why bother" category. Sure, you'll have great frame rates at high resolution, but they go out of date just as quickly as the upper mid-range cards. As soon as the next DirectX comes out your card is obsolete. I rode my FX 5900 till it couldn't play games (as it sort of overheated and took out my motherboard in the process), then I rode my X1650 Pro till it died, then I rode my 8800 GTS till it died, then I rode my HD 4890 till it couldn't play new games, then I rode my R9 270X till it died, and I'm happy enough with my RX 470 now. The thing is that my high end cards went obsolete or died just as fast as my midrange cards and I wasn't unhappy with any of them. Spending $800 on a graphics card is pointless. Just get a 1070 or a 1080. Use the money you saved to get more games, or put it towards a VR headset.
