I own an HP Pavilion a250n with a P4 2.6GHz (800 MHz FSB) HT processor, 1.5GB RAM, 550W Antec SmartPower2 PSU, among some other unnoted hardware. I currently have an overclocked ATi Radeon 9600SE installed with the GPU at 369 MHz and the memory at 248 MHz. (original 324, 196 respectively) I'm looking to upgrade the video card one last time in this old heap before upgrading to PCI-e. I have limited my selection to two video cards, the Geforce 7600GT and 7800GS and I had a few questions. First and foremost, will this processor bottleneck? I figured with the HT, that it would be significantly better with bottlenecking as compared to the same specs, but without HT. I'd rather not spend the money on a card that my computer can't handle. If it can handle it, does anyone have the benchmarks for these two cards? They are rather close in price, my other concern is which is overall better. As of now, I'm favoring this one: Link Thanks. Edit: I ran into a slight confusion on Everest. When looking at my FSB, it gives two read outs, real clock and effective clock. Real clock is 200Mhz and effective is 800MHz. Can someone clear those two terms up for me? Thanks.
