Ok, at first i though it was my PSU (which still could be) but does a 3DMark05 score of 8600 seem right for an X1900Xt flashed to XTX bios and OC'd to 650/770 (using ATI Tool)
My System is as follows
P4 630 3.0ghz @ 3.8ghz
Aqua Gate mini R80
1 GB corsair XMS Pro DDR2675mhz
Sapphire X1900Xt Flashed to XTX @ 650/770
Using 6.3 Cat's
Rosewill 500W PSU
HP Lightscriber dvd/cd burner
Mitsumi Floppy Drive, card reader
