Hello guys,

I'm building my first PC. I want to choose a video card for my PC, but as I see almost every ones I want are working with PCI Express 2.1 However, I can't find any motherboards with a PCI Express 2.1 slot, so there have to be something wrong no?

Also, I have chosen a motherboard with an integrated video card (HD 4250) and it supports Crossfire Hybrid. I want to buy a separate video card for my PC, but I read that I shouldn't use an integrated video card combiened with a separate video card because it would be less performant than a motherboard with no video card integrated and a separate video card. Is that true?

Finally, I have another question that is not related in the category Graphics but if you could answer me here it would avoid me posting another thread. I want 8 GB of RAM, so should I buy 4 x 2GB or 2x 4GB, or is it the same thing?

Thanks for replying quickly

PCI-Express 2.1 is backwards-compatible with 2.0. Rest assured, your GPU will fit in the motherboard, I can almost guarantee that if it's one currently on the market. Could you link the motherboard model here? That would make things easier.

Integrated graphics automatically are disabled unless you enable the Hybrid Crossfire setup, which is an energy-saving configuration. Since it'll cause your system to switch between the integrated graphics and the added GPU as it feels is needed, it does have a noticeable performance loss. However, pretty much any dedicated video card over $100 (and some that are cheaper) will outperform the 4250 if it is used alone, and you do NOT have to have the integrated graphics active.

Common consensus (that I've seen) is that you should stack RAM as high as you can in as few slots as you can.... So long as you fill at least 2 slots (dual-channel). So I will say 2 4GB sticks.
