New PC what get n stuff?

[smt]

Ok so my current PC is:

Operating System
   MS Windows 7 Ultimate 32-bit SP1
CPU
   AMD Athlon 64 X2 5000+   
RAM
   4.0GB Dual-Channel DDR2
Graphics
   AMD Radeon 5770
Hard Drives
   200GB Seagate
   150GB Seagate

I'm sorry if I made you jealous with my PC, anyway...

I know what I'm doing with computers, but I wanna get opinions on what I should get, as it's my birthday coming up and I'm planning on totally upgrading my PC. The one issue is, neither me or my parents have enough money for an AMAZING PC, or hardly enough for a mid range one, so I was thinking getting something like an AMD Phenom II X4 965 3.4GHz, which would inturn require a motherboard & RAM upgrade, so I was planning just any old AM3 mobo & 4/8gb ram, I just can't get it cheap enough, really I can't go over £300 (fuck yeah cheap parents & unemployed teen), so wat do?

tl;dr need a new pc, keeping graphics card, very low budget, pls help

also dont link me prebuilt crap, I'm looking into getting a barbones bundle though cause they're sometimes pretty cheap

My suggestion, cheep computers tend to be shit, dont get them, however, look into CyberpowerPC.com, they have some cool builds.

 Try upgrading your current PC. It's cheaper than getting a new one.

like (i think) i said, upgrading almost any part makes it necessary to get an entire new PC, I don't wanna be stuck on AM2 cpu's cause they're all really bottlenecking my graphics card gaming wise
