You're right FixT, an odd comparison to be sure. I got both at decent prices so ended up with an odd choice. For now I'm likely to toss in an AMD 1090T with a M4A89GTD, with an OC to 4GHz w/VCore 1.41V. Might be able to get a cheap HD5770 or GTX 460 but that's not the main concern at the moment since I haven't gamed in 3 years now =(. All air cooling, with no plans for water cooling or modding. About 5-6 hard drives, 4 optical drives.
This PC is likely going to be a hobbyist server for Oracle, MySQL, and various web server apps like Weblogic, Apache, IIS etc. Also likely to do a lot of development work, mainly with Microsoft Win and Web apps, so Visual Studio, SSRS, MSSQL stuff, with subversion and sprinting tools installed.
I'd dearly love to get a nice i7 build going but funds are low, and I have the other parts lying around at hand at the moment, there's only a small chance I might sell them and do an Intel build.
Edit: Forgot to mention I'm likely going to set it up to do Folding over the weekends...FAH has killed 3 computers of mines on the 3 times I've tried to set it up, so 4th time's the charm
