Bulding a new computer and I need a little help.

^ what he said, but the 650TX has a much larger rebate, and ends up only being $10 more that the 520HX. The HX is modular, which means prettier cables and wire management than the TX, but the HX has 3, 18a rails, and for 8800GT's nvidia recommends 22a, 26a for the 8800GTS 640, so you may have to parrallel 2 rails together to get the amperage, but the 650TX has one big nasty 54a rail so you can hook anything up to it.

both are good psu's though

P.S. the vid card doesn't actually draw that much but it wants to leave room for other components on that rail. You have to try and evenly distribute everything when you have multiple rails.

no clue what "rails" are (this is the first computer ive ever built) and umm i guess i'll go with the 650 TX

EDIT: how come i can edit all my other posts but i cannot edit my first post??????

rails are like bus bars... your power is split up in to 3 rails so you can't put more than 18amps of devices on 1 rail. nVidia recommends putting the 8800GT on a 22a rail minimum so you don't overload it with other devices. the TX has 1 big rail so you can just put everything on it without worrying about load distribution. If it were a $25 difference that might be one thing but with the bigger rebate making it only a $10 difference I think it's worth going with the TX. I was planning on a 750TX but might drop down to a 650, dunno, I want to see what the power requirements of the new dual core gpu's are when they come out. They ar supposed to be pretty efficient so 650 may be plenty.

im going to get the 750 tx for sure, might be useful for future upgrades, also i was looking at these two processors:

Newegg.com - Intel Core 2 Duo E6850 Conroe 3.0GHz 4M shared L2 Cache LGA 775 65W Dual-Core Processor - Retail

and

Newegg.com - Intel Core 2 Duo E8400 3.0GHz 6MB L2 Cache LGA 775 Dual-Core Processor - Retail

the second one looks like its better but it costs less, why?

also you said "mobo is good for one gpu..." doesnt everyone only have one graphics card?

and should i get the same graphics card that i said in my first post? the 8800GTS?

edit: about the graphics card, you said the one in my original post, the 8800gts was based off the g80 but i see this one

Newegg.com - BFG Tech BFGE88512GTSE GeForce 8800GTS (G92) 512MB 256-bit GDDR3 PCI Express 2.0 HDCP Ready SLI Supported Video Card - Retail

is an 8800gts based off the g92 series. dont you think that is better? but if so, why is it cheaper?

well the wolfdale, and the g92, are cheaper because they are better performing revisions for the most part. There's not as much money put in to R&D like with an all new product.

Get the E8400

No, some motherboards support 2 3 and even 4 vid cards, the one you picked only has 1 PCI-E x16 slot

The 8800GTS 320 and 640 are g80... the 512 is g92. the g80's are more expensive because they aren't producing them anymore and aren't trying to push them like the g92 512. They're hoping people with an old 1 will pay it so they can have 2 in SLI probably.
I would say get an 8800GT512, it's almost as good as an 8800GTS 512, better than an 8800GTS 320 or 640, and cheaper than all.
If you can wait, in a couple days the 3870 X2 card will be out, and in feb the 9800GX2

ok i'll get the e8400, its better and cheaper so why not? also the motherboard, you said mine supports two at x8, does that mean it wont support my 1 (im only buying 1 gpu) at full speed? or it will support it at full speed? and also i think i'll get the 8800 gts 512 because the 8800 gt is ALMOST but almost doesnt cut it for me and i dont mind spending a few extra $$$, as for the 3870 X2 card, no clue what that is or how much it'll cost etc btw im not ordering this pc for like 2 weeks so i have plenty of time to plan it out

no I screwed up, yours(DS3L) only has 1 PCI-E x16 slot, not 2 at x8. but yeah, some have 2 slots and will handle 1 at x16, but when you put in two they back down to x8, which is still plenty or todays vid cards, but others with 2 PCI-E x16 mobo's can run both at x16,x16

I think the 8800GTS is like 10% better than the GT but 30% more expensive. The 3870X2 is basically 2 3870's on one card, will be $400 or $450 and the 9800GX2 will be 2 8800GT's on 1 card I believe, but with GDDR4 memory

sounds good, anyone have any suggestions about other parts?
