I don’t have a specific recommendation, but here’s how I go about buying computer equipment. First I figure out what the system requirements are. Then I check sites like Newegg to see what matches those requirements and read all of the reviews to get an idea of what is good and bad. Then I’ll follow some sites like slickdeals to see what is out there for a bargain. Anyway, someone will probably have a better, specific recommendation, but that will get you started. (If you’re running something like Photoshop, you’ll probably focus on getting a good graphics card and lots of ram)
