Performance comparison between these two cards?

[harris1986]

Hi guys i'm looking at getting a new gfx card - now i have found a £7900gtx 512mb with clocks of
# Memory Clock : 1.6 GHz
# Clock rate : 650 MHz
# Chipset : 7900 GTX
for £349

but i want to know if it will really be a noticeable performance difference against the 7900gt 256mb XXX extreme edition which has clocks of
# Memory Clock : 1630 mHz
# Clock rate : 550 MHz
# Chipset : 7900 GT
which oc have for £276?

Is the GTX 512mb really worth the extra £73?

the highest res i'l be running is 1280x1024 really and that's only for FEAR

hmmz true, but is £73 really justifiable? would you think the GT would run FEAR comfortably and quake4? i'm not really a big gamer i tend to play cs1.6 and source mainly.

look at my sig i have a x1800xt 512mb atm, and it's just too buggy for me :S, has put me off ATi, and after reading a diff forum a guy has got his gt to 600 / 1800 on air. also found a 450 / 1320 for £199 inc vat + del new

haha well said lol, aye 7900gt it is then , now i got the choice of either getting the 550/1630 for £258 or the 450/1320 for £199 inc del + vat?

 

[harris1986]

thinking about it as i have just sold my x1800xt 512 for £220 on everyones favourite auction site then i'm going to get the 550/1630 version as it will only cos me £38 not bad that
