I built an old top end AGP rig for testing.
Asrock 865PE motherboard, modded bios to support wolfdale. I dont have better AGP motherboard, but i think a fast core 2 is not limiting these cards.
I have a lot of lga775 cpus i did not want to use quad core because it was almost useless for retro gaming so i stayed with dual core, first is used an E6750 but when i modded the bios i selected newer wolfdale Core2 E5300@3,4ghz cpu (i do have E8400 but it not works in this motherboard, there is no support for 1333 fsb wolfdale, only with the conroe)
Stock Intel Cooler, the cpu is cool even with overclocking (i only raised the fsb to 1066, no extra voltage or ram divider change)
2x1Gb Kingston brand average DDR1 400@440
120Gb Kingston SSD
Evga 600w psu
So i have test a few VGA cards with 3dmark01se, WindowsXP
So first a very slow FX5600XT (i think it is the slowest 5600 ever made, 64bit ram)
It is hot, slow and ugly.
For next it was the budget king, i chose a very low end Msi MX440 64bit, but i overclocked a bit (300/600). Funny it is FASTER than the FX5600XT
Yes the low end fx series is that bad that a low profile 64bit mx440 can beat it. So it is possible a beter mx440-460 can beat the non LE/XT version of the FX5600.
Next is a still low end FX5600 but with 128bit memory. Much better than the XT variant.
Ok so i bored with the low end stuff next is Leadtek A280Le despite is an LE card it is much more better than the Fx5600 nearly double performance in 3dmark01se (DX7/DX8)
It is a Ti4200-8x so it can overclock for 300/600, almost all 4200 can handle these clocks. i have lost the picture about the card, it is a single fan version with big heatsink that cools the vrams.
And time for non native AGP cards ( PCIe-AGP bridge chip on the card)
Inno 7600Gs overclocked
MSI 6600GT but it was with the slower cpu E6750 (2,66ghz 1333fsb) Not overclocked.
I do have a lot of AGP cards but very little time for testing.
The bad thing is the motherboard not supports 3.3v cards only the universal and the 1.5v cards. Is there any voltage converter adapter?
