User experience will be poor in many respects.
5900 RPM hard drive is much slower than 7200 RPM drives are. I would strongly advise you use a 7200 RPM hard drive instead.
I will take a look at the 7200 ones
Motherboard is overkill.
XFX 650w would do better for the same price compared to the Corsair 650w.
The AMD RAM just hit the market and has a very short track record. I wouldn't buy it on that basis. It could be awesome or it could completely suck, but either way I wouldn't want to suggest you to be their test victim.
If you are going to use a 64 bit OS, almost all motherboards can handle RAM with the part number CT2KIT51264BA1339 and it has rock bottom failure rates. It is about as close to the ideal set of RAM as anything in existence.
which type of ram would you recommend?
If you have a 32 bit OS, you should stick with 2 x 2 GBs instead because that is all that will be recognized anyway.
Havent purchased the setup yet, still need to get a OS
Processor - I would rather see you get an i5-2500k and a Gigabyte 1155 motherboard to go with it instead of this processor/board. The FX series AMD processors were a flop in the marketplace, that is why there is almost never a time there is not a host of price reduction and combo deals that include them. It is the only way that sellers can offload their inventory.
How are the AMD Phantom II fx http://www.newegg.com/Product/Product.aspx?Item=N82E16819103913 any better? i was orginally going to get an i5-2500k but was told by a few people AMD preformed better. What motherboard would you reccomend to go with the i5-2500k if i were to go that route.
Case - I would switch it out for an Antec 300 or HAF 912 instead. The bargain basement CM 430 won't do well at the main job of a case which is helping to increase the lifespawn of the parts inside it through adequate airflow and cooling. Both of the above entry level enthusiast cases are much better for systems that are going to include 6900 series cards
Good to know, i mostly just like the look on that case. havent settled on it yet
The XFX 6950 uses a dispersal fan which means most of the heat is going to stay in the case when it comes off the fins. The CM 430, iirc, has a top mount PSU which means all that heat has to get sucked into the PSU which will drastically decrease its lifespan.
Both of the above cases have bottom mount PSUs which means all that hot air from the video cards doesn't get sucked right into the PSU. This pretty much doubles its life expectancy.
If you are willing to spend maybe 10 - 20% more on the build you will have much better performance and life expectancy out of the system.
