4 GB RAM @ 1866 MHz (about 2.8 usable b/c 512MB is dedicated to the GPU and the other 700 went somewhere...)
500 GB W.D. 5400 RPM
My question: Should i get a graphics card and just crossfire it with the 7660d or should i get another 4GB of RAM because i usually use most of it up. I do some lightweight gaming, like COD, Just Cause 2, Mirrors Edge and source games. I also stream so I want to know which would help performance more? RAM or a GPU? I was looking at the 6570 1GB to Crossfire with the 7660d.
Well...are you having trouble playing games?
When you play games, open the task manager and see if you're using up all of your RAM.
When I play some more intensive games, sometimes they will crash. I use almost of all of my RAM streaming and that gets frustrating. I was thinking maybe the graphics card would take the edge off my RAM when playing because of the integrated graphics?
At $60, you're better off just upgrading your RAM to 8gb. If your motherboard has open ram slots, buy the same kit of ram you bought before. Otherwise, if you can spend a bit more than 60, grab this RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
The 2400mhz speed will definitely help because your using an APU.
Don't waste your money on the 6450 or 6570. The 7660D integrated GPU is equivalent to a 6670.
60$ will get you an extra 4gb of ram... But mixing Ram doesn't always work even if you get the exact same you have right now. Also, for 60$ you wont find a gpu that will be much better than your apu. Sorry
