A bit more information on your intended use of this computer would greatly assist us in narrowing down the thousands of options available to you.
It also wouldn't hurt to give us a ballpark budget, otherwise it's just a shot in the dark. Here's something at the top end of the spectrum, you probably don't need it, but I had fun putting it together to illustrate my point.
If you find you want something a bit more reasonably priced, we can do that to, just let us know what you want to use the comp for and how much your looking to spend. _________________
