I've just upgraded and had a right episode. My mother destroyed a hard disk, motherboard, and 256mb of ram by turning my pc off incorrectly despite me telling her what would happen
I then found that nobody is selling the old 32bit athlon boards now, and as I want to play the odd game or two on my machine I had to spend more than I'd originally budgetted for as I didn't want a sempron 64, I knew I'd be better spending the extra and getting a skt939 athlon 3200+ 64 instead. Still got 512mb of ram even tho i lost a stick.
I thought alright, spent a bit more than I planned but got a pretty damn good machine now.
Bought my gear at lunchtime then went back to work. While at work I came to the realisation this board had a PCI-E slot for the gfx card, and no AGP slot. My card was AGP!
Had to go back and shell out another £80 on a decent graphics card
Felt like 'd royally shafted myself, and there were no other boards with 3 ram slots so I couldn't just swap the board
Ended up spending £250 when I'd planned originally to spend about a ton
At least I got a good machine now lol.
I bought an Nvidia Geforce 6600, but not the GT version and it's great
