except 10gb is, like, really small. If you're running XP on that it would be tight. Of course it would be low on 256 too. Although based on your specs I would guess that you're running an older OS.
RAM - 10GB is enough, don't let them tell you otherwise. I mean, unless you've got like movies and lots of games and stuff. Then you DEFENITELY need more RAM, and you'll need a bigger HDD
well i would proubly go with memory. because having more memory is always great! you know wat i mean? lol i could spare hd space. buy not memory. 1gb is still not enough for my games. and memory lag is worse than low fps. so get memory.
Yeah, you're gonna want a new computer...If not that, I have a 20gb and a 40gb HDD that i'll never use again, i'll sell those to you cheap, and then you'll have money left over for RAM.
