My specs are:
Athon 64 3500+
ASRock DualSATA2
1Gb Corsair
I ran a 7800 GT and got 2489 in 3DMark06
Running the x1800 XT got me 2499.
Is the 3500+ fast enough to run a x1800? I'm not sure it is as the upgrade only yielded a 10 point gain.
i believe ur system is strong enough not to limit the video card.
3dmark06 is synthetic. i mean it can give u an idea about the power of the card but it is not real life. that is if u are not playing 3dmark.
my personal opinion is that ati x1800xt is better than 7800gtx but not by much. i personally like ati but recently i bought a nvidia card because it is superior in that class, that is lowend. i went from r9000 to r9200 to r9500 softmoded to r9700 and than i bought the leadtek 6200 agp card wich can be modded to 6600 and can easily be overclocked very much getting it close to the performance of 6600gt making it a middle range performance.
let's get back to our discussion. i believe in using raw power the smart way and that is what ati is doing. now i believe the discussion is chainging because x1900xtx is here and levels everything in its path, including the highly overclocked and virtual video card that 7800gtx512 is.
