Silvertwister

Also, for Yomatiase, your 2008 iMac should have a Geforce 8800 GS in it. That's one generation above the minimum specs required by the game, so while you will see a significant improvement in performance compared to parallels, you will still be fairly limited in how high you can turn up the graphics.

To help you all better understand what you're experiencing, Parallels and VM Fusion are both virtual machines with no direct access to your graphics hardware and with reduced access to CPU and memory thanks to what is called a virtualization layer. Boot Camp is designed to run Windows more or less natively as if you had a PC with drivers that directly access all of your hardware normally (because despite all the extra money you spend on a Mac, a Mac and a PC have the exact same hardware in them). This is why games that use 3D rendering perform abysmally on Parallels and VM Fusion but Boot Camp seems to run them well. When gaming, go Boot Camp all the way. Also, if you don't already have one, grab a two button mouse.

You won't be able to max it all out, but you should be able to run high textures and decent lighting and geometry.

I'd reccommend an MSI in the same price and equipment range if you're going for newegg. They look and feel better IMO and this one is new, not a refurb, for close to the same price: http://www.newegg.com/Product/Product.aspx?Item=N82E16834152369 If you can move a little higher in your budget, you could get something really nice like this: http://www.xoticpc.com/msi-gt70-0nd444us-p-4987.html
