I have very little knowledge in what the difference is in who manufactures the card but this is the one I have. I will start off with a single card but I am looking to get another one of these to do crossfire with.
Now this is where you guys might look at me funny... I know I will be running 2 of these 300 dollars cards but my friend works at best buy and got me a really good deal on it. Anyhow, I am on a very tight budget.
My 2 main games that I play is world of warcraft and starcraft 2 but I will also like this computer to run other games like call of duty and the new star wars mmo when it comes out. (On high settings)
Now when I said I was on a tight budget, I mean a tight budget. LOL. So I found this processor
Additional Comments: I have the AMD Radeon HD 6870 already. Just need to know a good CPU and Mobo pretty much, and perhaps recommend an affordable tower. Ram, HD, and power supply, I will take care of myself as well. I will just need to know how much power I should get and what type of ram but all in all, I just need to choose a mobo and cpu. I would like a mobo that will allow me to upgrade to a better processor as well in the future so I don't need to buy a whole new motherboard.
I don't think $200 is practical to do an intel build. It can be done but I think an AMD processor will be better for your needs. Also, I know you didn't list newegg.ca as a place to purchase parts but they have great prices and excellent customer service. If you don't use them I would recommend Canada Computers over Tiger Direct as they have much better prices.
As far as overclocking and SLI/Crossfire, that is not possible for your budget. You will need a better cooler for the CPU and a motherboard that has 2 pcie ports that run at least x8/x8. For your 6870, I would recommend the following.
This is the fastest triple-core Athlon II available, and it sports an ideal combination of three execution cores, a high clock rate, a low price, and respectable overclocking headroom. Despite the deceptively low buy-in, this processor delivers some serious gaming capability. It is such a great gaming CPU, in fact, that it almost renders most of the CPUs in the $100 to $130 range overkill.
^+1 for the X3. A dual slot CF motherboard with a cheap price? The cheapest in my country is around $70. But since you're in Canada, should be cheaper. The best is the 790FX/890FX (both lanes at x16). You don't need an IGP anyway, which narrows down your options. The alternative would be a both x8 PCIe motherboard. I forgot which model though (too lazy to google ).
Finally, a $50 Team Elite 2 x 2GB DDR3 RAM and you're all set!
Just curious, what PSU are you using? Since the HD6870 is a pretty power demanding GPU.
