I just overclocked the crap out of my X800XL and destroyed it. Half the pollygons are torn (badly, worst I have seen) and mis-rendered in games and my desktop has artifacting all over it. What I'm wondering is if I should replace it with another X800XL (free) or if I should pay the difference for a 7800GT (BFG). The difference would be about $130 ($380). I don't think our store carries the 7800GTX and I didn't really want to pay that much. Just wondering if the 7800GT is worth it, or if I should just get the X800XL for free and pay the difference for a 7800GTX down the road. Any input would be apreciated.
