It's called a desktop. Just like gaming, laptops are particularly ill suited to high end graphics work. Smaller, lower resolution, displays, slower and lower powered CPUs, slower and lower powered GPUs, not to mention the fact that there is physically less room for all the waste heat from the CPU and GPU to go. So it just sits around inside the case, raising the ambient temp, and slow baking everything inside the unit.
What you want is a desktop, and not some dinky little slimline unit or all-in-one unit either. You want yourself a full fledged mid-tower case.
As for brands... Personally I'd suggest staying away from anything made by HP or Acer, so: HP and Compaq, then Acer, Gateway, and eMachines. I'd also be a bit wary of Asus. From what I'm hearing about some of their back end things, like dealing with repairs, they're making stuff up as they go... Right now. That says something about the company to me, and it's not anything good. Beyond that, don't go into a place like Best Buy or Fry's and buy the cheapest thing on the floor. Any desktop sub-$500 should be avoided like a leper with the plague. Something in the $1,000-$1,500 (or higher) is where you probably want to be looking. Otherwise, there's little to no profit margin on the unit, and it's what you call a loss leader. Companies produce them with the hopes of making up the losses they take on the back end. So they load them with all kinds of crap software, there's little to no upgrade potential (so you have to buy another one soon), and just about every little dirty underhanded trick they can come up with will get pulled on you. Plus, if you're getting paid say a few pennies for every unit of a particular model you inspect, and a couple of dollars to inspect units from another model... Which one are you going to spend more time on? Quite probably one of the best and worst things to happen to the world was the sub-$2,000 computer.
That said... Dell is pretty good... Apple's Mac Pro would be an excellent choice if you can swing that kind of cash. You could probably even reconsider HP if you're paying $1,500+ for a unit. I'd still stay away from Acer. There just aren't that many companies left in the market. Years of deregulation and ever narrowing profit margins have reduced the playing field considerably.
