there's a guy in the buy/sell forum selling a brand new x1800xl for $220 SHIPPED. you can probably bring that down to $200. thats equivalent to a 7800gt (better in my opinion
) and there's a chance you can overclock that to x1800xt speeds (or 7800gtx/7900gt). all that for something about the same price as a 7600gt. i'd get it but i have no money. just a heads up..
oh and if i had to choose b/w 6800gs and 7600gt, i'd take the 7600gt. the guy that had hard time OCing it just didn't get lucky i guess... because i've seen (can't recall where...) ppl OC it quite nicely. and as you mentioned earlier the features of the 7*** series... !!
