Hi all, Please bear with me, as I'm very much a newbie. I'm looking at the following two GeForce 6600GT AGP video cards: GIGABYTE GV-N66T128VP Geforce 6600GT 128MB 128-bit GDDR3 VIVO AGP 4X/8X Video Card http://www.newegg.com/Product/Product.asp?Item=N82E16814125179 eVGA 128-A8-N350 Geforce 6600GT 128MB 128-bit GDDR3 AGP 4X/8X Video Card http://www.newegg.com/Product/Product.asp?Item=N82E16814130220 Is brand a considerable factor to consider? Is the difference in performance truly worth $45? (I actually found the Gigabyte card at zipzoomfly.com for $10 less, but that's still a notable gap in price.) I noticed a Sapphire Radeon x800GT 256MB card on newegg for only a few dollars more, so is that perhaps the best course? I would greatly appreciate any insight into the differences. Thank you very much for your time and patience.
