So I can get the ASUS GTX460 1GB "TOP" (OC'ed) for $175 brand new, wondering if its worth the upgrade for me... I currently have an 8800GT 512MB, old yes, but still chugs along. My PSU is an Enermax 460W 80+, will that be enough juice to power the GTX460? The rest of my system is an E8400 with 2GB DDR2, random HDDs and I am hooking up a 22" Acer and my 32" LCD to the card. So I figure HDMI will be a plus for hooking up the TV (currently I have DVI-->VGA). Is this a good deal for this card?
