My Graphic card now is 8600 GTS 256 MB , i bought the HD 5770 Vapor-X GDRR5 and make bottleneck in my system , people said me that my computer is old for this card and with OC maybe can work good . i thought that maybe the GTS 250 could work well on my computer. My monitor is a CRT 17 "
Im player of counter strike and left 4 dead and i play with low resolutions. And the subject in OC the problem is that I am a newbie and I have fear of doing it wrong. Sorry for my english .
