I'm unsure if I should wait to build this system or build it now. My current computer runs the games I play decently. The only games I play right now are League of Legends and Starcraft 2. And in the future I would play Diablo 3. I'm not going to be playing BF3 or other high intensive FPS games.
Should I wait for HD7000 series? Should I wait for Ivy Bridge?
Plenty of reviews have shown that 1600MHz is the sweetspot in terms of price and performance and anything above that is usually not worth the extra cost. I can provide links to support this if you want to see evidence.
Mushkin Enhanced Blackline Frostbyte PC3-12800 8GB 2X4GB DDR3-1600 9-9-9-24 1.5V $53/$43 http://ncix.com/products/?sku=60640&vpn=996995&manufact...
This looks like one of the best price/performance units on NCIX:
XFX Pro 750W XXX Edition 80Plus Silver Modular $115/$85 http://ncix.com/products/?sku=62224&vpn=P1750BNLG9&manu...
For 6870 crossfire a 650W is easily enough, but I haven't noticed any 650W PSUs that are clearly better than the XFX for a similar price.
The P8Z68-V, which would have been another option, doesn't have a PS/2 port. There are adapters which mean you can plug a PS/2 motherboard into a USB port.
I don't think it matters which chipset you get, unless you want to have the 'backup/troubleshooting' option of having access to the integrated graphics.
I don't know much about Ivy Bridge, but I can't imagine that it will offer much for gaming that Sandy Bridge doesn't. Some people might mention PCIe 3.0. But graphics cards won't need that extra bandwidth for years.
OTOH if you don't have a pressing need to upgrade yet, then you might as well wait. And is probably what I would do.
With next generation graphics cards around the corner that is another reason to wait.
Thank you very much. I edited some of my parts to reflect your input. I know I'm probably overkilling this system, since Starcraft 2, League of Legends, and Diablo 3 are not very CPU + GPU intensive.
Since this system seems to be overkill for these games, is there a point in waiting for the new hardware that's coming in the future? With the HD7000 series right around the corner, will that even be a choice for me? Does anybody think that there will be a price drop in the 6800 and 6900 cards?
