Considering memory for new [gaming/general] build

Seeing that RAM prices are going up, I would like to buy the RAM for my new system sooner rather than later.
I will probably get an Intel C2Q, but if the budget tightens up I may end up with an e6600 or an AMD 6000+ instead. I may not be able to finalize that decision for another three weeks, but I am wondering if there is a definite best memory choice in any event.
Overclocking, if any, will be slight (making the 6000+ viable vs. a C2D). My biggest concern is about compatibility with regard to voltages; I can see that the timings of my choices are different.

Here are the choices I am considering. Please note that my case is a Micro-ATX:

MOBO:

If AMD:
BIOSTAR TA690G AM2 Socket AM2 AMD 690G Micro ATX AMD Motherboard With HDMI Port - $90

If Intel:
GIGABYTE GA-G33M-DS2R LGA 775 Intel G33 Micro ATX Intel Motherboard - $135

RAM:
1. mushkin 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - $100

2. G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - $90
http://www.newegg.com/product/product.asp?item=N82E16820231098
3. SUPER TALENT 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - $106
http://www.newegg.com/product/product.asp?item=N82E16820609026

Whatever I choose I'll want to be compatible with either board. If I go Intel, I'm pretty set on that Gigabyte; if I go AMD I'm open to suggestion.

Any suggestions are appreciated. Mods, please feel free to move to General Home Built, but this is mostly a RAM question. Thanks for your patience.
 
MoBo for AMD processor and nVidia Graphx: look into this one before going straight AMD/ATi. One bad, its out of stock right now. 🙁

Memory: spend $5 for 4-4-4-12 GSkill PC6400. But it might boot-up as 5-5-5-15 @ 1.8V. Just set to 1.95V and 4-4-4-12 in BIOS (NOT windows!).

Due to memory/FSB/HT timings, I'd go with the AM2 5600 @ 2.8GHz over the 6000. As you may or may not know, the E6600 has a hidden feature if you use a P35 board (Gigabyte preferred). Just change the 4x266 FSB to 4x333, and you get a free upgrade to an E6750. There is a small graphx improvement by doing it (2-4%), and a larger operations improvement (5-8% depending on apps). Some of the P35 boards are reasonably priced, and if you save $50 over your original choice, then you can afford a Q6600 with the same little secret.

Unfortunately, due to crappy heatsinks all of these CPU's neet a better cooler. If you're willing to take a performance hit consider the AMD Brisbane 4000, these can be o/c from 2.1GHz normal to 2.67 GHz using the included heatsink/fan. A $5 tube of Artic Silver 5 will make this ideal. If the case you pick has good airflow try for 2.80 GHz. It has been done. Choosing the AMD Brisbane 4000 will save you $80 compared to the 5600 (which can't o/c to save its life) and about $140 over the E6600 that can go upto 3.40 GHz with coolers, fans, more case fans, etc.

Its good to be king.

Thanks for the links. The RAM definitely looks good; I may order it later today.
I'm using the X-QPACK2 case: http://www.newegg.com/product/product.asp?item=N82E16811144140
...which has front and rear fans. I will be getting an aftermarket cooler (need to recheck the case for fit; probably a 7000 series Zalman or one of the shorter Zerotherm tower-style); the AS-5 is already waiting for it.
For a PC I expect to last a few years, I am not willing to take a performance hit. I really hope the Q6600 is in my budget.
The only P35 boards I saw were ATX, which is not an option in my case.
I see that MSI has a new G33 board now; cheaper than the Gigabyte but with 2 more USB and 2 eSATA ports; I may switch to that:

Still, I like Gigabyte's reputation. We'll see.
