Hi Guys,

Quite a few questions i'm afraid but I would be grateful for your help.
Im looking at putting together a new computer but have a few questions about different specs.

1. In terms of RAM why is it that people seem to stick to the 1600Mhz RAM when the 2400Mhz sticks don't seem to much more expensive?

2. With the DIMM slots for the RAM is it a good idea to populate them all or does that sometimes affect the quad channel ability or performance of the RAM?

3. What about the voltage of the RAM? If I have a lot of high speed RAM do I need a beefier power supply?

4. Can certain processors handle different speeds of RAM and memory channels?

5. I heard that most applications/games only use 4 cores so is it only worth investing in a 4 core processor?

6. If I have more than a 4 core processor will I benifit when using multiple applications as they will use different groups of 4 cores (if that makes any sense)?

7. With graphics cards when in SLI do I need them to both be in a motherboard that can support x16 on both in terms of bandwith as well as physical pci slot?

8. With graphics cards in SLI can I use the monitor outputs from both graphics cards or just one?

9. If I have two graphics cards not in SLI and I start an application which is graphics intensive will it still just use one?

I think that is the only questions I have for now but i'm sure I will have more as I seem to be struggling to understand all this.

I greatly appreciate any input. Thanks in advance.
 
Wow thanks for all the great responses.

Based on what you have said I was looking at this RAM:

http://www.overclockers.co.uk/showproduct.php?prodid=MY-315-CS&groupid=701&catid=8&subcat=

That seems like a good amount of fast, low latency RAM.

In terms of CPU I was looking at this one:

http://www.overclockers.co.uk/showproduct.php?prodid=CP-403-IN&groupid=701&catid=6&subcat=567

Seems like a good Quad core i7

I don't think I will be doing any overclocking as that is a bit beyond me and I want the build to be very reliable.
 
Thank you,

That RAM is a lot cheaper, would you recommend overclocking that as well?

I wanted to avoid overclocking any of the system because I want it to run reliably for up to 10 hours a day and also because I have no clue about overclocking or what I need to do or change.

Is it something I should just bite the bullet and try and learn about or can I get away with not overclocking by spending a bit more money?

Thanks again for all your input so far
 
Another question in addition to the above, if I have a graphics card with HDMI out can I just use a HDMI splitter to send the same signal to several monitors/tvs? Will this affect framerates in games at all?
 
Sorry I don't mean to reject cheaper options as it is always nice to save money I just didn't want to sacrifice performance in any way and am willing to spend the money if there is a faster option
