I should mention I'm not a gamer. I use my PC for Internet surfing, photoshop and indesign and audio/music recording. I'll be connecting it to my TV and using it as my central media centre at some stage too - so I want to future-proof now a little bit.
Unfortunately the mobo link you posted doesn't lead to a mobo page. I can't find any mobo's for $70 at UMart - not at the Sunshine Coast store I'll be shopping at anyway.
I'm still not sure whether the processing power of the i5 will benefit me more than the the extra cores on the Phenom - I often use multiple programs at once and I've read that's where 4 cores will come in handy. I looked at the best value chip link, but it constantly refers to gaming performance, which I'm not that interested in.
