1.33 Ghz is really old, I'd rather save the money for a completely new system. I have gotten my new system (3.2 Ghz celeron, 2 Gig ram, Vista) for just 530 Euro, if you can spend a bit more you can also get a better processor and more Ram. I'd suggest 4 Gig if you can afford it, then you can even handle large scenes. IMO its not good to still invest money in such an old system, even if it can hold enough ram, the ram will be slower and 1.33 Ghz will be too slow for the next version softwares i guess. I used my old system untill it "died", good i didnt invest anything more into it, so i could afford the 2 Gig Ram version. ^^
