Maximum PC

Hey there. My current build is acting very finicky, and I think it's either a motherboard or memory issue.

My current specs are:
-Intel Core 2 Quad Q6600
-GIGABYTE GA-P35-DS3R
-nVidea GTX 260
-Cooler Master Cosmos 1000 Case


I'm looking to replace the case, motherboard, processor, and memory with this:
-Case: LIAN LI PC-9F Black Aluminum ATX Mid Tower Computer Case
-Mother Board: GIGABYTE GA-Z68A-D3H-B3 LGA 1155 Intel Z68
-Processor: Intel Core i3-2100 Sandy Bridge 3.1GHz
-Memory: G.SKILL Ripjaws Series

I don't really game anymore, this will a workstation for web browsing, email, and some photoshop work. So I may sell the GTX 260 and just go with the on board graphics above.

Let me know if you can do better (with price or performance).
