the 810 doesn't have a set amount of memory, but takes up to 11 MB of system memory depending on what it is doing. regardless, it sucks pretty bad

however, despite its suckitude, it is better than a voodoo1. when i owned an 810 system (it is now my girlfriend's) i put a voodoo
2 in it and got a great increase in speed. v2's are really cheap ($12 in some places), so i would go buy 2 of those and run them in SLI or (assuming you can disbble the onboard video on your motherboard, which you can't do on all systems) go get a nice voodoo3 PCI of geforce2MX PCI.
