So I have a Acer Aspire X3400 although I have modified it a bit and I have a PSU around 500W and I'm also using a Radeon HD 2600XT but it only has 300mb of memory... My current specs are:
Radeon HD 2600XT - 300mb (NVidia 9200 Integrated) GPU
AMD Athlon 2 X2 220 - 2.8GHz CPU
500gb HDD Seagate (I have another one if needed) Hard Drive
DA061/078L-AM3 Motherboard
5gb DDR3
RAM (2 x 2GB, 1 x 1GB)
Windows 10 x64 OS
~500W PSU
