well i could upgrade the psu too if i have to, what would be a good combo of psu and graphics card, for not much money? also i should be able to turn off the 6150 in the bios menu right?
If you could upgrade your PSU too then this is a pretty nice combo.http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.492784
Your CPU might already be a bottleneck for this card so going with something more expensive and powerful would just be a waste.
Yes you should be able to turn off the integrated graphics in your bios menu.
