Thanks for all the answers :)
I feel enlightened :D

I'm new to pc building and that kind of stuff, and I am in the middle of the process of building one myself. I've seen alot of people talk about "Bottlenecking" and that a cpu might "bottleneck" a grapchics card.

Could someone explain what this is and give some examples of it?

Anyone?

I am in the process of building a pc. It seems like the Radeon 4870 HD is a decent graphics card, and the AMD Phenom II X4 940 Black Edition seems like a decent processor. I have not yet decided what motherboard to buy. I would like something pretty cheap, but it also has to be pretty decent and go well with the graphics card and the processor.

All suggestions are welcome, and I'd just love an input on what kind of RAM to choose as well :)

Thanks for the info :)

I've also noticed that there are some tempting AMD triple-core processors- Are Triple-cores considered to be any good?

Well, I'm building a pc now. I'm mainly aiming to play Arma 2, and I'd like decent performance (on semi-high graphics. I also expect future patches to optimize the game better). I have already decided that I will get the Radeon HD 4870 1GB (please comment on this), but I have not decided on what processor to get.

I've been checking up on the AMD Phenom II X4 940 Black Edition, but it seems like it will be too expensive for me :/ Could you guys suggest a decent, but cheap processor? As I said, I would like to be able to play Arma 2 with decent performance (and graphics), but I'd also like to play some older games.

Looking foreward to suggestions :D
