|"i can't upgrade my computer to something like your Super P3 to make it a tualatin 1.4 ghz processor with 2gb mem :)"|
Unfortunately, Coppermine CPUs are slower than Tualatins, clock-for-clock. But, if you run any multi-threaded apps on that rig, your dual Coppermine-933 may be able to beat my single Tualatin @ 1.66GHz.
I've tried the following cards with Super P3 (I'll also list the 3DMark 01 scores to give you an idea of how much my CPU limited the newer cards):
Radeon 9800 Pro - no problem. 3D'01=14380)
Radeon X800XT All-in-Wonder - didn't work so well, artifacts were present while playing DXVA-accelerated video content, BSOD in certain games. 3D'01=15810. This card worked fine on an nForce 2 (Athlon XP) board.
GeForce 7950GT - no problem. The fastest gamer of the bunch (for some reason, it was even faster than the HD3850). 3D'01 score was 19634.
Radeon HD3850 - no problem. full H.264/VC-1 video decoding actually let me play Blu-Ray discs on the Super P3 (I have a thread about that here on computing.net). However, my CPU must have really been limiting the performance of the 3850, as the 7950GT managed to beat this card on every game and benchmark I ran. The 3850 scored 18089 in 3DMark 01.
The Super P3 now belongs to the kids, and it's currently running a Sapphire HD3650 (512MB DDR2) card. This card lets the kids watch the 1080p MKVs that I've made from my Blu-Ray collection. Also handles simple kids' games very well.
"x1650xt agp = 134 in US dollars
hd 3650 ddr2 agp = 81 in US dollars
x1650 pro ddr2 agp = 51 to 57 in US dollars
Inno3D/Sparkle 7600GS 256ddr2 = 46 in US dollars"
The HD3650 is the only card that supports DirectX 10 and full 1080p video decoding. Speed is similar to the older HD2600 Pro. It's the best card on your list.
"i will be using xp sp3 , i dont have a vista. which do u think should i buy ? "
Probably XP for a sub-GHz machine with PC133 memory.
" i hope it will work on my motherboard ( asus cuv4x-d i really need help here ) "
Should work. My Super P3 is built around the newer (but similar) VIA Apollo Pro 266T chipset (Tualatin support with DDR memory).
Pentium M oc'ed to 2.82GHz, 667FSB, 2MB L2
