Hardward for a Core i7 hackintosh

Hello,

I am planning to buy a new PC. Like most users here, I too would have bought an iMac, but for the price :( . I am looking for a decent configuration, since I will be using it for Web development. Running Photoshop, Zend Studio and three browsers with 20 tabs open is making my MacBook crawl. It would be really helpful for me, if someone could help with the configuration. I am looking for a configuration that is known to work and have a good performance.

In case, hackintosh turns out to be a bad idea, I wish to fall back to Ubuntu with virtual box for running Photoshop.

Thanks,
Vinod
