I'm upgrading/building my PC. I could use some advice

I am planning on upgrading my PC parts and have already made a list of all the parts. I'm not the best at this kind of stuff so if you guys could verify that all these parts look good that would be very helpful.

Case2: http://www.newegg.com/Product/Product.aspx?Item=N82E16811146087 (I prefer this one and will most likely choose it)

CPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16819113284  (I am open to any other suggestions for a different cpu) - (I currently own an AMD Phenom II 955 @ 3.6 ghz and plan on waiting a little longer before buying the new cpu.)

GPU: I honesly have no idea what I should get, if you could suggest that would be great. (I currently own an HD 6870 and I also plan on waiting a little while before I buy a new GPU)

You'd probably want 1866 ram not 1333. It's better for overclocking and helps with AMD cpu's. Apart from that, everything looks good, and you can probably wait on upgrading your CPU and GPU for a bit, They still aren't completely outdated yet and can play most games.

I second the faster RAM. I also agree that you can ride out the CPU a bit longer. As for the GPU, The 7870 XT (Tahiti LE) is a great value, while delivering performance similar to a 7950.

I too support the faster RAM cause. Also, continuing on with the current CPU is a very good idea, but you should also probably hold on the graphics update until the new generation comes out and is either really impressive, or just shoves the price of the old ones down the toilet. Then you can get a 7970 and feel good about yourself. Otherwise, the 7870 XT is an excellent option. Umm, case-wise it really depends on what you like the appearance of as they both have pretty similar functionality. I just couldn't get past the peculiar appearance of the Phantom 410. I think it is one of the ugliest things on the face of the earth. However, I do really like the Source 220, and I'll be buying that one for my next build if they still have it around by then. I intend on punching a side panel window into it and repainting the whole thing. Probably something tasteful, like orange. Or maybe red, it depends on which motherboard I go with. As it stands I like the ASRock Extreme9 990FX board because it is absolutely bonkers and it is a really good price for the performance potential, but it doesn't mesh well with my sense of aesthetic, so the motherboard coolers would be coming off and getting diassembled for a good spraying with paint. Probably to match the case, not sure yet. As far as the RAM is concerned, the Patriot Viper 3 series is really really very pretty, and they technically go all the way to 2400 MHz in the series, so the 2133 MHz can be made to go that far if you are really gentle with it. Either way, past 2133 you are just splitting hairs to find any real improvents until you hit 2800 MHz.
