As of yesterday, I've spent just over R30000 in over 2 years building my system up. I'm just waiting for my last parts to arrive from Prophecy, and I'll be set to go.
My main killers were the 24" BenQ, and the 8800GTX. And the Intel Q9450 come to think of it. Yet my system isn't totally up to what I want, I only have 400 gigs hard drive space, and I still want a tv card, and perhaps 4 more gigs of ram. Also want to get equipment so I can join the Cape Town WUG.
Yes, the cost has been insane. Yet is was my dream when I started, and I don't think I'll ever be able to do it again, so I bought something to last. While it's not cutting edge anymore, it will play almost every game at the full 1920x1200, except for Crysis. And that is all I really need.
Luckily I don't have a wife or girlfriend or things like that, so that is how I used my cash.
