well had to ask, I expected more due to the results of one card, none the less not bad, thanks.

Hmm that score does seem fairly low for a XP setup. My previous comp was almost identical, it was an oc'ed 6000 to 3.5Ghz and that setup took me on Vista 64 to 13/14k. Now i have the same cards not clocked with an oc'ed E8400 and hit 18739. So it most likely is your CPU not giving your gfx cards as much room as they need to breath.

My rig atm is the same bar the CPU only reason i think it's your problem. As for what you can do well you can overclock but that goes against your no overclock statement so i guess cpu an mobo upgrade is the only other way.

To be honest if your gaming a 22" screen or less you'll be running games at almost max anyway. The only reason i upgraded was because i wanted to get past the 4Ghz barrier and the purchase of my 24" Sam'y.

Ah another thought, I'm unsure of your experience with 3DMark, but to get the highest scores you need to go into Catalyst Control Center and set all the 3D options to let the application decide, all the sliders to performance and disable Adaptive AA. Remember after benching to reset all these as they can affect your in-game gfx i.e game options high but visually it'll be poor.
