Review my New, First Moderate Gaming Build

I've been doing the research for a year now, reading all the reviews I can find and waiting patiently for the latest tech to come out (waited until reviews of ATI's 3800's were published). Finally, I've ordered it yesterday morning, and I'm hoping it all arrives by Monday, with the video card making it here a few days following the bulk of it. This is my first homemade build, before this I've been using a modified Dell 8400 (Intel P4, 7600GT, 2GB Ram), so I'm really excited about this.
I have a friend to help me build it to, in case anything goes weird.
I expect to use this for moderate gaming, with the most demanding game being at least Oblivion, and possibly Crysis. So you know I'm not going to cheap out much on this one. I'm installing my legal copy of Windows XP Professional SP2 on this machine; I'm not sure if I'm going to upgrade to Vista, but I suspect I will eventually (not a fan of DRM).

So here are the components I selected, did I make good choices?

MOBO - GIGABYTE GA-P35-DS3L LGA 775 Intel P35 ATX Intel Motherboard
http://www.newegg.com/Product/Prod [...] 6813128059

I wanted to get a mobo that supports PCI Express 2.0 expansion ports, but it would either need to support SLI (I don't plan on getting ATI cards), or have just one PCI Express 2.0 slot... which is a board I haven't been able to find yet. So, I'm spending a little less money in this area on a board that supports everything else I'm looking for (SATAII, Core 2 Duo, etc), until my next upgrade which would be that first board I'm looking for.

CPU - Intel Core 2 Duo E4600 Allendale 2.4GHz 2MB L2 Cache LGA 775 65W Processor
http://www.newegg.com/Product/Prod [...] 6819115032

This is the one item I wasn't able to find many reviews on, there are only 2 reviews in the Newegg page alone, too. But I've read much on the success of the Core 2 Duo line and I believe it's still a safe purchase.
I wanted a 2.4GHz stock clock for the processor, but I'm a little concerned with the low FSB (800MHz). Should I be?

Memory - G.SKILL 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
http://www.newegg.com/Product/Prod [...] 6814130303

Probably the best buy in my whole build, this memory kit didn't even cost me $50. I've been using G. Skill on my modded 8400, and I haven't had any problems yet. I decided on these over a Patriot kit, anyone disagree on the choice?

Video Card - EVGA 512-P3-N802-A1 GeForce 8800GT Superclocked 512MB 256-bit GDDR3
http://www.newegg.com/Product/Prod [...] 6814130303

I'll admit, I did jump on this as soon as I saw it since they are becoming harder and harder to find by the day. I'm using an EVGA 7600GT right now and I'm not dissapointed, and this product comes with a lifetime warranty, so I feel safe.
My ideal build would've been one where I wouldn't have to upgrade the critical components often, like this video card. Since I made this choice, that list now goes down to only the motherboard, processor, and memory. I expect that I won't change those until at the earliest two years down the road, but I want to try and extend that as long as I can.

Power Supply - Antec True Power Trio TP3-650 ATX12V 650W Power Supply with Three 12V Rails
http://www.newegg.com/Product/Prod [...] 6817371001

It's certified at SLIZone.com to run two 8800GTS' in SLI, which was what I was originally looking for early this year. Since 8800GT's have shown in tests to draw less power than the GTS', I think I'm still in the safe.

Hard Drive - Seagate Barracuda 7200.10 ST3250410AS 250GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive
http://www.newegg.com/Product/Prod [...] 6822148262

It has that new 'Perpendicular Recording Technology'. 250GB is enough for me, initially.

Monitor - 24-inch Soyo LCD Widescreen
http://benchmarkreviews.com/index. [...] 3&Itemid=1

I picked this up at the Black Friday sale @ OfficeMax, it was priced at $250. So far no dead pixels or ghosting, so it's all good for me.

Case - COOLER MASTER Elite 330 RC-330-KKN1-GP Black SECC ATX Mid Tower Computer Case
http://www.newegg.com/Product/Prod [...] 6811119115

It houses my build, provides all the shelter it needs. Cost is cheap and if you ask me it looks better than the Centurion 5 (http://www.newegg.com/Product/Prod [...] 6811119068). Got an extra 120mm fan for the front for $7. Will the 8800GT be able to fit alright, do you think?

The total price (excluding the Power Supply and Monitor, bought elsewhere for cheaper) is $730.92.
With the PSU and monitor included, I believe it reaches $1045.

That's about it. On a range of 1 to 10, 10 being excellent, what do you rate? The
