Win 7 or win xp build? Is XP better in every way than 7?

[toms_hammer]

Going for a reliable, value gaming PC, so I picked older pieces with lots of newegg reviews: socket 775 motherboard/CPU + DDR2 RAM over an i5 or i7 build.
Thanks for any help. The questions are at the bottom. My main concerns are getting RAM that works without having to change any BIOS settings (“plug and play” RAM), and whether or not I should wait for out of stock pieces.

CPU
$195 e8500 3.16ghz dual core CPU Model:BX80570E8500
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115036&cm_re=e8500-_-19-115-036-_-Product
I think dual over quad, because faster cores and less power/heat.

MOTHERBOARD
$90 GA-EP45-UD3L (“OUT OF STOCK”)
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128372&Tpk=GA-EP45-UD3L
or
$80 GA-EP43-UD3L
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128380&Tpk=GA-EP43-UD3L
I choose gigabyte over asus, because it seems more reliable and better performing. The first mobo has a p45 chipset, which is suppsedly a little better for overclocking.

RAM
$105 g.skill 2x2gb DDR2 800 F2-6400CL4D-4GBPI-B, 450 newegg reviews, 5star avg

or

http://www.newegg.com/Product/Product.aspx?Item=N82E16820231122
The $105 RAM seems to be newer, has listed timings of 4-4-4-12, and has 1 reviewer saying he used it with GA-EP43-UD3L, the older P43 version of the motherboard I want.
The $90 RAM has listed timings of 5-5-5-15 and has 2 reviewers saying they used it with GA- EP45-UD3L, the motherboard I want but is out of stock.

HARD DRIVE, PRIMARY

VIDEO CARD

http://www.newegg.com/Product/Product.aspx?Item=N82E16814150438&cm_re=4890-_-14-150-438-_-Product
Or $200+ Radeon HD 5830?
Or $160+ Radeon HD 5770?
Toms hardware charts FPS charts show 4890 performing equally with 5830. I choose 4890 because it may be more reliable. Some bad recent reviews for the 5830s on newegg. 4890 and 5830 performed better than 5770.

POWER SUPPLY
$110 Corsair 750W PSU Model:CMPSU-750TX
http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006&Tpk=corsair%20750
I'd like the 750W over 650W just to be safe with these monster video cards that use a lot of energy.

Not planning to overclock. I just want to be safe.

OPERATING SYSTEM
XP 32 bit
or
Win 7 64 bit?

Total, with first choice for each, excluding OS price, is $1115.

Questions:
1. A GA-EP43-UD3L motherboard reviewer said he used F2-6400CL4D-4GBPI-B RAM with his build(which is why I want to get that RAM). Should the RAM also work for GA-EP45-UD3L(the P45 mobo I'd rather get)? Likewise, if a reviewer says such and such ram works for GA-EP45-UD3R or GA-EP45-UD3P, should it also work for GA-EP43-UD3L and GA-EP45-UD3L?

2. Should I wait for the P45 gigabyte motherboard, the newer X25M SSD, and the HD 4890 to be in stock, or go with the alternatives? Anyone know how long it will take them to come back in stock, or know of any website that tracks newegg item availability history? And which memory and OS should I get?

3. Why did newegg stop selling GA-EP45-UR3R and GA-EP45-UD3P motherboards? Those were a couple of their most popular boards.

4. Does anyone have a link for G.skill's RAM naming scheme?

5. Will 5-5-5-15 DDR2 800 ram be faster than 6-6-6-18 DDR2 1066 RAM? Will it be faster than 6-6-6-18 DDR3 1066 RAM?

6. Does anyone know the difference between the above 2 solid state disks? And does anyone know the difference in performance/features between the older SSDSA2MH080G2C1/ SSDSA2MH080G2R5 and the newer SSDSA2M080G2GC / SSDSA2M080G2GN?

8. These HD 4XXX and 5XXX video cards say they require at least a 500W PSU. Should I go with an 850W PSU to be safe or is 750 fine? Using only 1 video card. Using 2 hard drives: 1 traditional and 1 intel SSD.

9. Why I haven't been able to find sites with graphs showing XP performing better than 7? After googling “win 7 vs xp”, the sites from the first two pages of google have graphs showing win 7 performing about equal with xp, but a good amount of commenters at the bottom say things like xp is better than 7 in every way. (e.g. http://www.maximumpc.com/article/reviews/windows_7_review ) If that's true, how come I didn't find any sites with graphs showing XP performing significantly better?

10. It seems like newegg offers weekly discounts and combo deals on their items that don't sell so well. Would it not make them more money to offer deals on items that do sell well?

11. How high could this build be overclocked? What about with 1066 RAM? And with what FSB speeds? Or is it better to keep the RAM timings low?

12. Does anyone know a good place I can get a new $300 - $500 laptop that has win XP installed instead of 7 or vista? Or if I already own a copy of XP, can I install it on any new laptop? Would anyone recommend ebay for buying a used laptop?

Please fill out the builders template - link in my signature.

Also, not sure where you can find a new laptop with XP installed. I think dell my still allow for it, but I think it costs money to "downgrade."

However, I believe that most people are now of the opinion that 7 is better than XP, and a 64-bit system is much better than a 32-bit system, particularly with new builds. You can use more RAM with a 64-bit system. (XP-64 has always had problems - drivers and compatibility issues).

Windows 7 is superior. (And I haven't even used it yet). Not sure why you would really want an antiquated build for a new build either. Not sure of the complete rationale, but please put that information into the Template.
