My original Asus GeForce2 GTS (bought for £180, 2 years ago) has served me very well but its becoming yesterday's news and i'm really considering the upgrade to an MSI GeForce4 TI4200 (http://www.watford.co.uk/products/search.asp?search=3&sku=28756&Shoplink=18) when its released. Obviously alongside an overall motherboard, CPU, ddr333 ram upgrade. In general, how much % faster is the GF4 from my GF2 considering all the architectural improvements because i can't find any benchmarks that still use a GF2 for comparison to see 4 myself? Another interesting thing I noticed on this site was: "MSI's card is equipped with 3.5ns RAM while SUMA's sports 3.3ns. Theoretically, the memory can operate at speeds above 550MHz." Meaning I could buy a very good value for money TI4200 and overclock safely to near TI4400 levels. Finally, what justification do i need to get the TI4200 with 128MB ddr memory when there is also the same card but with 64MB ddr memory that is cheaper?
