Hello all. I am hoping to be able to run some more games on my Acer Aspire T180. I was wondering if i was able to use a XFX HD-667X-CDF3 Radeon HD 6670 2GB 128-Bit DDR3 PCI Express 2.1 Video Card on my 300 watt power supply. My system specs are currently 3gb ram, AMD Athlon X2 5200 @ 2.7 Ghz, Nvidia Geforce 6100 256 mb integrated. Thanks.
