Your selection looks pretty good. You have chosen one of the best cpu on the market. It also gives you the option of overclocking to help keep up with future cpu's to be released....so the need of not having to upgrade for a while is good on that end.
You cant beat that price for the ram that you have chosen...Cas 7 ddr3 1333 is pretty much the same as cas 9 ddr3 1600. You might even be able to get that RAM to reach 1600 but might have to back off the timings a little.
The PSU you selected is powerful enough....you might want to look at some reviews of it and see how it hold up under testing. One thing you could look in to is a modular psu...it will help you keep your build cleaner without all the extra cables.....plus if you dont have a case with good cable routing a modular will help with air flow as the cables will not be in the way.
Thank you for your input. There is one more question that I have:
Wouldn't it be better to get this GPU twice? Would I need to get a better PSU? Radeon HD 6850 1GB
Like I said, I'm just trying to play the currently released games at the best quality possible while keeping the 800$ budget. I'm just using a single 1650x1080 monitor.
Also, I'm not trying to upgrade anytime soon again.
1650x1080 can be run more than fine on the GTX 570. It's even slightly overkill. Matter of fact, you could even downgrade to something like the HD 6950 1GB version or even the HD 6870.
My advice would be to grab an HD 6870. For your gamig needs, it's as good as you can get, without bursting your money out the window too early. The 650W psu will handle the xfire configuration at a later time without worries
6850 crossfire is fine with a 650 watt psu. I would get the second card but remember that all games do not support crossfire/sli so you would get better performance with just one card in games that don't support
Thank you very much for your time to help me out here.
I like your idea and I'll certainly keep it in mind. I have already saved all the hardware pieces to bookmarks.
I don't plan on upgrading any time soon. (~5 years) That includes getting a second GPU at a later point. Or do you think getting a 2nd GPU with the 560ti will be a reasonable and cheap upgrade in 2 years?
If I got a single 560ti, would that be a bottleneck in games, considering the CPU?
If yes, should I stick with the 570 then and get a cheaper motherboard and stay with the PSU?
the 2500k cpu and the 560 ti will have no bottleneck. If you can afford the 570 I would go for it....cheaper in the end for an sli config would be the 560...depends on you...performace wise both in sli will beat 580.
