Hi guys, I would like to ask for some advice on building a new rig for my dad. Erm, the budget would be around 2k SGD. So that makes it about 1.3 -1.5k USD. Erm the rig is more for photoshop and digital imaging as my dad is a photographer. Could anyone please suggest some parts to get a solid rig. I'm thinking Core 2 Quad here but please do give me advice. Also, for photo editing, is it neccessary to get a SLI computer? Thanks for your time.
