I want to buy one of these two graphic cards, but i can`t decide between them, their price is similar, and performace also,
what do you think?
Always go for the higher number - 6800
Unless you plan on doing duel 6600 GT SLI, go for the 6800. If you have a bit more cash on you, the 6800 GT.
I have a BFG 6800GT OC and I've got it overclocked very close to the 6800 Ultra clock speeds with no special cooling. It's a great card and it keeps on chugging. I'd recommend the 6800.
I'd go for the 6800 and buy a Artic Cooling Silencer 5(I think) and overclock the hell out of it.
Some PRICES:
MSI NX7800GTX-VT2D256E $449.00
MSI NX6800GT-T2D256E $289.00
MSI NX6800-TD128E $189.99
MSI NX6600GT-TD128E $150.00
SAPPHIRE 100133 Radeon X1800XL $369.00
The 6800 costs 26.7% more then the 6600gt
(189.99 / 150 * 100 - 100 = 26.66)
But the 6800 only performs 14.3% better then the 6600gt
I have an MSI 6600GT AGP on one of my computers, and my new eVGA 7800GT PCI-E came in yesterday. Honestly, the 6600GT doesn't compare, and I am sure the 6800 would be blown away too. I say save up for a 7800GT / GTX or buy a 6800 with an aftermarket fan/heatsink and OC the hell out of it.
