Depends on how much they cost, if you can get a 7900GT for the same price as the 7800GTX, go with that. I'm not really sure how a 7800GTX and a 7900GS compare, but I think the 7900GS would be weaker, since it has less pixel pipelines.
Sorry- If I can get a 7900GT for the same price as 7800GTX I should go for which one>? :/ I guess 7900GT but need to make sure
7900GT, its the same pipelines, but a newer core on a better fabrication process(the 7900GT is on 90nm where the 7800GTX is 110nm). The 7900GT has higher clocks, runs cooler, and can overclock better, so go for one of them all the way. Here in the states the 7900GTs are a bit cheaper then the 7800GTXs, so there really is no reason to pick up a 7800GTX.
yeah totally the 7900gt... slightly newer technology always has better benefits... well nearly always!!!
to be honest why upgrade, the 7800GTX is still a great card and will play all games. You would be better off sticking with the 7800GTX and waiting to see what DX10 cards are released. ATI had yet to release and nvidia are yet to relaese a mid-range card. most likly the 8600 which would own a 7900GTX! lol! Im just saying wait for a while as 7800's dont differ that much from the 7900's.
I dont thing he already has a 7800GTX. I think he has neither at the moment. If he DID have a GTX Id say keep it, 'cos I can run anything I throw at mine, and that's at 1920x1200, but it is heavily overclocked and watercooled. If buying a new card tho, Id go for the 7900GT.
Stock a 7800gtx is faster than a 7900gs but the gs will overclock really well and the gtx carnt keep up because they dont clock that high (gs can get 600+ core) 7900gt will obvioulsy be faster than both however!
The 7900GT isn't that much faster than the 7800GTX, they have near enuf same clocks, it when it comes to overclocking that the 7900GT really shines over the 7800GTX.
Go with a 7950 GT is you can its almost as fast as a 7900 GTX and with a little bit of ocing you can reach 79 GTX speeds no problem.
