I am building a PC with this motherboard: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It will have the Xeon E3-1275V2, and 8 gigs of ram. But I cannot decide on which graphics card to buy, I could go with the integrated graphics, a Radeon HD 3870 X2, or A Radeon HD 6850. I am leaning towards the 3870 X2 because of the low price, and high clock speed, but the integrated graphics are fast too. I would just be basically playing games like GTA IV, I would just like to know if any would be able to play it with maximum or close to maximum settings.
I would really appreciate it if someone would help me decide which one to use, or suggest me a better one for the price.
This card shouldn't even be still sold. It's a dual-GPU chip based on really old technology. The HD3870, HD4870, HD5870, HD6870 are older models replaced by the HD7870. It's about 5 years old.
The best value is an HD6850 or HD6870 depending on your price.
FYI, GTA IV is very poorly coded and doesn't run well compared to similarly looking games.
I thought of getting a Z77 board too, but with the latest bios update this board has almost the features of a Z77 board, like support for the 22nm CPU's, support for the faster ram, and DirectX 11 support with the onboard video, and PCIE 3.0, But considering that I may have to also buy an older CPU to update the bios to support the newer processor, I might go with the one that you said to buy.
