Hello, I was wondering a little more about the Nvidia vs ATI for dx 10 and previous games. I bought a 570 and noticed it does not run certain games (such as Arma2) like how I would want them to. My other question, is that the new processors have a 'graphics clock' built in, so would that add to the nvidia processing DX10 and previous games?
arma 2 is a pretty recent game and should run great on a gtx570. You should look at using different drivers and making sure the game is updated and windows/directx is updated. i dont know what you mean by "graphics clock built in" that makes no sense. A DX11 card has all the abilities a DX10 card has plus it has DX11 abilities, its not missing something a DX10 card has. If your having problems with ARMA 2 maybe you need to look into why, your gfx card i doubt would be the problem. From memory ARMA 2 is fairly CPU dependant. http://www.pcgameshardware.com/aid,687620/ArmA-2-tested... heres some baseline figures of what to expect. list your pc's full specs
The "new processors" you are talking about - do you mean Intel's new Sandy Bridge processors, with built in graphics? They do have a built in graphics processor, but only for people who dont want to buy a standalone graphics card. There are 2 types of motherboard for Sandy Bridge CPUs: P67 and H67. The P67 boards are for overclocking, and do NOT support the on-chip graphics. They just use the CPU as a CPU (a bloody fast one at that!). The H67 boards can be paired with a sandy bridge CPU and then you can run Intels new integrated graphics core. But you CANT overclock.
Using a dedicated GPU like your GTX 570 is possible on either motherboard type (p67 or h67) because all of the boards have a PCIExpress 16 slot on them. But if you had a h67 board with a GTX 570, the GTX 570 would BYPASS the on-chip graphics of the CPU. The on-chip graphics will NOT give a boost to the speed of the GTX 570. The GTX 570 is about 10x faster than the on-chip GPU anyway. But if you had an office computer then you could use the on-chip CPU and you would not need a dedicated graphics card.
Even a system-heavy game like Arma2 should run good on a GTX 570. The GTX 570 is a new and powerfull breed of card. Maybe you CPU is bottlenecking the game, if your CPU is 2 or 3 years old, and not very powerful then that would be the culprit. But you should check you are using the latest NVidia drivers:
