Help deciding between 2 video cards. Sapphire vs. Zotac?

I need help deciding which video card to buy. I plan on using it to play games, mainly racing games such as Need for Speed Undercover and other games such as The Sims 2 and Fallout 3. Please help me decide which one has specifications best for me. The sapphire has more core clock speed but the zotac has more memory clock speed.



Here are the cards:



SAPPHIRE 100236L Radeon HD 3650 512MB 128-bit GDDR2 PCI Express 2.0 x16

Chipset: ATI 3650

Core Clock; 720Mhz

Memory Clock: 500Mhz

120 Stream Processing Units



ZOTAC ZT-86TES2P-FSR GeForce 8600 GT 512MB 128-bit GDDR3 PCI Express x16

Chipset: NVIDIA 8600GT

Core Clock: 540Mhz

Memory Clock: 1400Mhz

32 Stream Processing Units





Which one do you think would bring out the best performance for gaming. Meaning less lag when graphics are set to high.



Thanks for your help.|||They'll be very close. I don't think either of them is a very good gaming card, unless you liked older games.



You would do much better in your preferred games with a more serious card, like a 9600GT or 8800GT or ATI 3870
