About the middle of last year I built a gaming PC on a shoestring budget (NZ$550 + free graphics card). This is what I ended up with:
Motherboard: Gigabyte GA-M57SLI-S4 (Rev. 2.0?)
CPU: AMD Athlon 64 3500+ AM2
RAM: 2 x Apacer 1GB DDR2 800MHz RAM
HDD: Seagate 160GB 7200RPM SATA
Graphics: ATI Radeon X550 256MB
PSU: 300W w/ one SATA plug, no PCI-E plugs.
Optical: CD-RW (already had) - Recently upgraded to a ASUS Lightscribe Super Multi SATA DVD burner
I am soon to get a spare NZ$500, and possibly another NZ$600 on top of that from selling another 2 computers, and so am looking to upgrade graphics. I was considering a pair of 8800GTs, but am now eyeing the (soon to be released) 9800GX2, with the possibility of a second in the distant future.
The rest of the system is likely to stay the same for a while; the CPU may be upgraded to a high-end dual core, or possibly Phenom Quad, but that is quite low down on the list.
My question to the resident populus is: what power supply should I be looking at getting? I am assuming that it will be at least 500W, but should I future-proof and go for 800-1000W? Modular would be preferable, and a blue LED fan would be nice (but that's just me being fussy!)
You are now free to start hurling the chairs around!
