You confused the 8570 desktop graphics card with the 8570d which is the igpu on some a8 apus. The 640 is almost double the performance.
I'm sorry if I wasn't clear, but I had meant the 8570D, which is the iGPU on the A8-6600K APU from AMD.
I have personally had a better expeirience with nVidia for graphics cards. Also, I'm looking to convert my system to Intel platform (it currently has an A8-6600K with 8570D) with a pentium G3258 and a MSI motherboard. Micro Center is offering a bundle for them for a steal, so I thought this would be my chance.
Thank you Tom's hardware!
