Difference in these 2 cards?

ok here are 2 evga 8800gts cards. ones a bit more expensive by a few dollars. Which one should I get? what is the difference????

first one:
EVGA 320-P2-N811-AR GeForce 8800GTS 320MB 320-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card - Retail

Second one:
EVGA 320-P2-N815-AR GeForce 8800GTS 320MB 320-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card - Retail

the more expensive one has:

576//1700 clocks

tthe cheaper one has

500//1600 clocks

Quick google search of both model numbers led me to EVGA's site

so I should pay the extra few bucks and get th emore expensive one?

Doesn't really matter, I'd say it's worth it. I'm sure you'd probably be able to OC the cheaper one with some better cooling though.

yeah true. k thanks man
