I am currently running it on an older system along with win2000. It's a p4 2ghz with 512mb ram and an ATI card. I really like it, however it seems to lag alot for some reason and has graphics problems. I am building a new system(650i, e6550, 8500gt, 2gigs ram) and I plan on installing ubuntu on it first and then further down the road pick up vista when I have the cash. will fiesty fawn work better on my newer system as far as compatibility issues? also, will I have trouble installing vista onto a seperate drive after ubuntu is already installed, or do I need to re-format and install vista first?
