this card is for the following new system that i'm specing:
Asus P5W DH Deluxe WiFi (Socket 775) PCI-Express DDR2 Motherboard
Intel Core 2 DUO E6600 "LGA775 Conroe" 2.40GHz (1066FSB) - Retail
G.Skill 2GB DDR2 HZ PC2-6400 (2x1GB) CAS4 Dual Channel Kit
EVGA GeForce 7900 GT KO SuperClocked 512MB GDDR3 HDTV-Out/Dual DVI
Antec TruePower 2.0 550W PSU
Seagate Barracuda 7200.10 250GB ST3250620AS SATA-II 16MB Cache - OEM
Pioneer DVR-111D 16x16 DVD±RW Dual Layer ReWriter - (Beige) OEM
Lian-Li PC-60 PLUS Silver Aluminium Midi-Tower Case
Creative Sound Blaster X-Fi Xtreme Music - OEM
I'm trying to keep the budget as tight as possible, so i was wondering weather saving the equivalent of US$55 and going for the 256mb version would be worth it?
I should point out that in the UK prices are different to the US and a 1900xt costs the equivalent of US$80 more than the 7900GT KO 512mb. otherwise i would be going for that.
