You guys are wasting bandwidth.  

What is the motherboard make and model?

Yes, 300w is not enough.

Mainboard
Bus(es) : ISA AGP PCI IMB USB i2c/SMBus
MP Support : 1 Processor(s)
MP APIC : Yes
System BIOS : Phoenix Technologies, LTD 6.00 PG
Mainboard : SiS-741
Total Memory : 512MB DDR-SDRAM

Chipset 1
Model : Elitegroup Computer Sys SiS741 CPU to PCI Bridge
Front Side Bus Speed : 2x 166MHz (332MHz data rate)
Total Memory : 512MB DDR-SDRAM
Memory Bus Speed : 2x 166MHz (332MHz data rate)

P.S. what about with the sempron? would it be ok then? or have i gotta go for like 400W either way?

If you need more than that i can A) give you it from CPU-Z or B) try and look inside it (i really cant see the model although it is 100% SiS (it has that on it yet no model number... weird huh?))

also what sort of performance increase would i get if i put more ram in? (1GB or something)

I don't think extra ram would give much of a boost considering the rest of your system.

This graphics card needs only a 250w power supply, and costs about £30. I suspect it's faster than your current card, but I don't know for sure.
