I might buy this PC with other 2 addition (PSU/Video card) tomorrow if i decided.

HP Pavilion a6130n Desktop PC-649$

AMD Athlon 64 X2 5000+ (2.60GHz)

RAM-3GB of 667MHz DDR2 SDRAM (PC2-5300) (expandable up to 4GB of ram)

Bus speed 2000 MHz

Level 2 cache 2 x 512KB

video card-NVIDIA® GeForceTM 6150 SE graphics with up to 632MB of video memory

PCI-Express x16 slot

WITH

replacing PSU 300 watt?*probably that rangewith buying this

ULTRA ULT31848 X-Finity 600W PSU Black100$

WITH replacing that suxy NVIDIA® GeForceTM 6150 SE graphics with up to 632MB of video memory to used this onboard PCI-Express x16 slot
