TheAria007 :
I have a
AMD Phenom X2 Black Edition Processor
4 gigs of ddr3 Ram
and have a gigabyte motherboard with onboard graphics of ATI Radeon Hd 4250 with Hybrid Crossfire X supported on my motherboard.
Can I go ahead and install a graphic card of ATI that will merge with my onboard graphics to give me faster performance, through CrossfireX.
thank you please help
You can however add an AMD/nVidia card as long as your motherboard has a PCIE slot, and run it by itself rather than in hybrid crossfire mode (essentially the GPU on your motherboard doesn't get used). It will be much much faster than what you have now. However, the power supply in your computer will be important for determining how powerful of a card you can get, so please post that information if you can. It would be good to make sure your motherboard has a slot for the GPU as well.
Simply adding a decent graphics card to your current PC will make your computer good for gaming (depending on your CPU it can be good or great), the GPU you have now is really bad for gaming.
Did you have a budget, or some cards already in mind? Are you gaming with the computer (what games and settings do you want) or something else?
Edit: Just to summarize from above, here are some considerations to keep in mind along with selecting your card:
Is the GPU (graphics card) going to be able to fit in your case, powerful cards can have trouble fitting in small cases. Also some cases not really designed to support full-height cards (the case would be really thin)?
Does your motherboard have a slot to plug a GPU in (a PCIE2.0 16x slot would be best, but PCIE1.0 is ok)?
Is the PSU in your system powerful enough to supply power to the GPU you want?
Is a new GPU going to speed up your computer in the way you want? (usually you only need a powerful GPU for gaming)
