Ok, in trying to buy a geforce 7900gt off newegg, I found three contenders; two are notable for being in stock.
the three are
ASUS Geforce 7900GT EN7900GT/2DHT/256M Video Card - Retail
in stock, cheapest, clocked at 430/1300
eVGA Geforce 7900GT 256-P2-N565-AX Video Card - Retail
clocked at 550/1580, most expensive, also in stock.
lastly, a variation of second card listed above.
clocked at 500/1500, not in stock; two times ive tried to order, but either my PSU or my graphics for my new rig is out of stock, and i want to order it all from newegg.
Ok, would the clock differences between the two evgas really account for a noticible difference? same question about the cheap one with low clock speeds and any of the evgas?
