Hey everyone I have been making many posts regarding me purchasing a new GPU and I have finally decided to purchase the 4850 PCS+ (665 MHZ) now there is a decision to be made here should i get the 512mb version for £120 or the 1gb version for £140 or is there something better or something cheaper but still as good for me to get Thank you.
E6400 Intel core 2 duo 2.13 ghz (non-oc)
ASUS P5N-SLI mobo
2gb ddr2 553 mhz ram
HEC 550-TD PTE PSU (35 A on 2 12v rails)
It compares the HD4870 ( a more powerful card than yours) between 512MB and 1GB. The end result: Although they did not see any big improvements with the extra 512MBs, they suggest you go for the 1GB version (small difference in price) because of the smoothness it provides.
I would also like to add that if you go at 1920x1200 and want to play Crysis as well, definitely go for the 1GB version.
If you get that high end card, I would definately overclock that cpu of yours to an easy 3GHz at least. Either that or upgrade to a faster cpu. I would never buy a high end card and be cpu bottlenecked.
