Greetings. You have to love TomsHardware. This place is like the Library of Congress for computers.

I researched about everything the last two weeks and came up with this config for a fair-budget gaming rig.

Case--HAF 912 $50
PSU---Cooler Master GX RS750-ACAAE3 750W $75
HD----Western Digital WD5002AALX $60
MB----ASRock Extreme 3 Gen 3 $130
CPU--i5 2500k $220
GPU--GTX 460 or GTX 560 $165-220
RAM--Ripjaws 1333Mhz, 1.5v $47
DVD--Sony OptiArc Burner $20

I had a few things I wasn't sure about. I'm looking to do as low cost a build now and add another vid card later in SLI, as well as an SSD and more ram.
-The Core i5 only supports up to 1333Mhz ram.
-Which vid card. 460 2GB or 560 1GB.
-If you don't overclock, is a CPU cooler neccessary.
-Lastly, 1 12v rail or 4 12v rails in the PSU? The articles I read here suggested 1 rail is fine.

Thanks in advance for any observations and suggestions. And Ripjaws has to be one of the coolest names given a pc component ever.

1) Core i5-2500K "supports" up to 1333 MHz, but 1600 MHz RAM can still be enabled to run at 1600 MHz in the BIOS

2) Are you talking about GTX 560 or GTX 560 Ti? Please specify. Also, I'd try to get a 6950 in that price range.

3) It might be necessary if the rest of your case cooling is bad or the ambient temps high; neither is the case for you. So try it out with a stock cooler, should be good. And yes, no point in getting a K CPU if you won't OC.

Thanks for the replies.

Since the k is only 20 bucks more I figured I get it now so I do have the option of overclocking. At that point I could also pick up a CPU cooler for $30.

Also, 1600Mhz was my first choice but some articles or threads suggested an i5 can only run up to 1333, which didn't make sense to me. Maybe they were older articles and at that date 1333 was top of the line.
I'll also change out the PSU.

Again, the feedback is appreciated.

One other thing I've been reading here is the idea of bread-boarding, or installing the main components on the mainboard and powering up and running various software stress tests to make sure everything works and works well before installing in the case. This sounds like the way to go.

Edit: For the Video Card, the GTX 560. The charts didn't show a huge advantage in going with the Ti.

560 Ti OC's nicely and it's definitely a lot better than the non-Ti.

Bread-boarding is a good idea, of course.

If you look at Intel's website, you'll see that 1333 MHz is indeed the maximum RAM freqency for i5-2500K. It wasn't changed. However, your board can change the BCLK of the CPU a bit in order to support higher-clocked RAM, IIRC. I'm not sure if this explanation is correct, but I'm definitely sure that all frequencies above 1333 MHz are provided by your motherboard - if it supports higher clocked RAM, you're safe.
