I'm going to quote from another forum:Originally Posted by dazed1992
As for all that timing stuff, here's another quote (from the same thread) which might be a little difficult to understand if you're new to this:If I were shopping for high quality memory, I would use the following parameters as a guide...
* DDR3 rated at 1.5v or lower
* DDR3 rated at the lowest CAS I could afford
* DDR3 rated at the highest clock speed I could afford
* Limit the scope of my purchease to G.Skill, Mushkin, Corsair XMS or Crucial (non-Ballistix)
While not wavering on the voltage point, I would balance the other issues with my budget.
Remember my goal is not pure "benchmarking" performance, but simply finding the highest quality memory I can afford.The only reason I pay a premium for low latency, high speed, low voltage memory is...
Quality and quality alone.1.5v is the JEDEC DDR3 voltage standard.
Stay with 1.5v or less if you can afford it..
I ran 20 clients in Orgrimmar off of 16GB of RAM, so I don't see why you couldn't run 11 off of 16GB. You could always just buy another set of DIMMs from your Newegg link for $40 and be done with it, unless you really want 32GB of RAM.Let's just do the math, the frequency is expressed in Hertz, which means "cycles per second". So, the DDR3 2133 will perform 2133 cycles a second while the DDR3 1600 will do, well, 1600. You, of course, know this.
Now the CAS latency is given in cycles. So, a CAS8 DIMM will take 8 cycles to respond and the CAS11, 11 cycles.
Now putting it all together - the DDR3 2133 CAS11 will take 11/2133 seconds, which is equal to 0.00516 seconds, to respond while the DDR3 1600 CAS 8 will take 8/1600, which is equal to 0,005 seconds, to respond. Thus, the 1600 DIMM is faster. For your dilemma, you're contemplating 0.000516 versus 0.00422 or timing difference of 0.00094 seconds! How fast are your reflexes and how long are you willing to wait for your memory to respond? Yes, I'm being an ass. You'll never ever see, feel or sense a difference.
You'll also want to carefully check the timings, since the higher the MHz the looser they are. I've seen 2133 DIMMS with 11-14-28-30, simply junk. As well as voltage, avoid anything higher than 1.5V. The only way many manufacturers get a respectable CAS at high MHz is to crank the voltage to 1.65V. Hence is why the 1.35V Samsung DIMMS are so smashing. Also, less DIMMs generally means less load to the memory controller. Therefore, 2x8GB is better than 4x4GB.
You want the fastest single-GPU video card with the most RAM that you can afford. Any of the choices you've linked above should work perfectly fine. I'm not really a fan of the 6xx series, but I don't know if I'd recommend AMD either since I haven't owned one in a long time.
It comes down to how much money you have to use for this upgrade. Do you want an SSD dedicated to your OS and your games? Do you want to split them up? Do you want them both on one big SSD? All I can say is... The larger the SSD, the better it performs (up to about 256GB).
