Decided to go with NZXT LEXA S LEXS - 001BK Black Steel ATX Mid Tower Computer Case

It has 2 SSDs bay so I do not need to buy adapter. It comes with 4 fans. It looks cool!

(already have) Monitor: Samsung Syncmaster 213T


Maybe overclock CPU/GPU in the future.

question1:

1. If I change RAM to Cas Latency 7 one, how much performance gain can I get?

2. I have no idea which PSU and CASE I whould pick.If someone could pick something cost less with same performance? Or just let me know your preference.

3. I have an old DVD burner IDE interface. Will it slow down the system? Or should I grab a SATA version.

4. If i7-920 only support DDR3 1333, why are we buying DDR3 1600? For overclock?

1) Not a whole lot. The numbers are the number of clock cycles it takes for the RAM to respond. From 8 to 7 is like overclocking the RAM by a couple hundred MHz. You probably won't notice the different.

2) Antec 900 and Corsair TX650.

3) Not really, but just get the SATA version, it's like, an additional $4? Anyway you won't see a difference because IDE can transport up to 100 MB/s and a CD or DVD can only transfer a few Megabytes per second, Maximum.

4) You could, or you could be like me. I left the i7 at standard clocks, and raised the memory multiplier from the standard 8x to 12x (20 seconds to do) and my RAM went up from 1066 to 1600 MHz. I never noticed a difference. The i7 technically only supports 800 and 1066 MHz memory, not even 1333. But if you were to leave the multiplier where it is, then it would be useful for overclocking. For example, if you have 1600 MHz ram and you overclock your i7 from 20x133 MHz to 20x200 MHz, then your RAM speed will go from 1066 MHz to ~1603 MHz. Therefore you're still safe on the RAM, which you wouldn't be with the standard 1066 MHz RAM.

I double checked the motherboard I listed. I found it only support Memory Standard DDR3 2200/1333/1066/800. Does it mean I can not use DDR3 1600? If so, maybe I should go with ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard

1 not much

2 the PSU if fine for a single card if you plan to add a 2nd HD 5770 get a Corsair 650W case for 10 buck more http://www.newegg.com/Product/Product.aspx?Item=N82E168... for 10 bucks less CM-690 http://www.newegg.com/Product/Product.aspx?Item=N82E168...

3 grab a SATA there not much 24 buck for a 24X http://www.newegg.com/Product/Product.aspx?Item=N82E168...

4 Yes



The reason I want to use my old DVD burner (possible PATA interface) is I can use all 6 SATA connector on the power for the hard drives. I want to make sure it will not slow down other SATA drives.

The ram will work on a lower frequency or the MOBO can overclock to 1600?

you can run 1600 ram at 1333 it might even tighten up your CL a bit or when you OC your CPU you want ram with higher clock speed so you dont have 1333 ram at 1600

I could not follow well. If I have DDR3 1600, can I run the RAM at 1600?
Since the MOBO does not support 1600, how can I run the RAM at 1600?
