Help with MB/RAM purchase for gaming rig.

Hello.

My PC, which I like to categorize as a gaming rig, has recently decided to bail out on me. The failing component was a disappointing-from-the-start Asus P5Q3 MB. I have a powerful GPU (ATI 4870 X2) and a raptor HD, and am very satisfied with both. After some consideration, I have decided to upgrade the machine to an i7 processor and triple channel DDR3. So here's what I want your advice for:
The MB: I have narrowed my selection down to Gigabyte GA-EX58-UD3R and Intel DX58SO as they both appear to be high quality products from companies I have yet to try despite planning to do so for quite a while. Considering price is not a factor, which of those 2 should I get my hands on?
Memory: This is a bit trickier for me, because I have always found it difficult to understand the significance of timing vs frequency etc. I have narrowed my selection down to:
OCZ GOLD DDR3 6GB 1600MHZ Model OCZ3602K - Timing 8-8-8-24
G.Skill 6GB Kit Trident DDR3 PC3-15000 1866MHZ - Timing 9-9-9-24
G.Skill 6GB Kit DDR3 PC3-16000 2000MHZ - Timing 9-9-9-27
Mushkin DDR3 6GB 1600MHz - Timing 7-8-7-20 (The one I'd pick)

It would be great if you could offer some insight on those RAMs compatability with the listed MBs (one of the problems I had with my deceased rig was that the Asus MB didn't take well to my OCZ memory.. I had to lower voltage, timing etc. to achieve stability).. That's it, Sorry for the wall of text. Any help will be greatly appreciated, thanks in advance.

Would be great if anyone offered a quick word, as I'm planning to go out and buy it soon. And I'm pretty much settled on the Mushkin RAM now.

Hello and welcome to the forums :) 
Between those motherboards,both are good, here are some good reviews for both motherboards,
Gigabyte model:

About the RAM,well if you aren't going to OverClock then go for the cheapest one because Timings/Mhz/Voltages are mainly important for OC'ng and they don't have a great impact on gaming,but if you are going to OC,then i would pick up the Mushkin model as well because of its lower timings.
And about the compatibility,it should work fine and remember that there are many RAMs that aren't listed on the motherboard's compatibility site but they will work with it fine

If I were building a gaming rig with an i7, I'd go with the Gigabyte or an Asus board. That's a nice gigabyte board you chose - the Asus I'd look at are the P6T and P6T Deluxe.

Thanks bunch for the input. I went with the Gigabyte and Mushkin setup, seems like a solid and decently priced choice.

I hae another question that started worrying me now: Will my PSU be able to handle the load of the new machine?
Right now I have:
Intel Core i7 920 2.66Ghz 8MB Cache Tray LGA 1366
Noctua NH-U12P SE1366 Intel LGA1366 Cpu Cooler
Gigabyte GA-EX58-UD3R Intel X58 Chipset Socket LGA 1366
Mushkin DDR3 6144MB (3x2048MB) 1600MHz CL 7-8-7-20 XP 998679
Western Digital 150Gb 10K RPM SATA II VelociRaptor 16MB
Samsung 1TB 32MB 7200RPM SATA II HD103SJ Spinpoint F3
ATI Radeon 4870 X2 2Gb DDR5 PCIE
CoolerMaster HAF-922 High Airflow Mid Tower chassis

The PSU is OCZ Fatal1ty Series 700W PSU SLi-Ready / 80+ Certified.

Thanks in advance once more.

I believe you should be fine. Many times the amperage on the 12v rail is a concern for graphics cards.

Check this PSU calculator out (not for an exact answer, but to get you close - at least a decent estimate)

I also have an Intel Core i7 920 and the Gigabyte GA-EX58-UD3R, but my videocard is a Radeon HD 5970 and I have a 650W Corsair PSU with no problems. I believe the 4870x2 draws a max of around 450W while the 5970 draws just under 300W, and because ATI recommends a 650W PSU for the 5970, I'd recommend getting something with 150W more than that. I could be wrong though.
