First Build, need opinions

Hey guys, I've been waiting till this summer for the new graphics cards to come out to build my first pc, and i have to say i already learned alot about the parts. Well anyway I want to use this computer for gaming, music production, browsing the internet, and the usual multimedia purposes. I wanted to keep the cost of just the pc at around $1100. Well anyway, this is what i came up with.

Motherboard = DFI BloodIron P35-T2RL LGA 775 Intel P35 ATX Intel Motherboard - Retail = $122.91 =http://www.newegg.com/Product/Product.aspx?Item=N82E16813136038

CPU = Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Quad-Core Processor - Retail = $199.99 = http://www.newegg.com/Product/Prod [...] 6819115017

GPU = ATI HD 4780 = $299.99

PSU = As of right now, i think a 650 watt psu will do fine, but I'm not sure how i should go about selecting one, since i have no idea how many connectors or w/e is needed for my gpu.

Ram = CORSAIR 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Retail = $66.50 = http://www.newegg.com/Product/Prod [...] 6820145184

Hard Drive = Western Digital Caviar SE16 WD5000AAKS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM = $79.99 = http://www.newegg.com/Product/Prod [...] 6822136073

Case = APEVIA X-CRUISER-BK Black Steel ATX Mid Tower Computer Case - Retail = $70.98 = http://www.newegg.com/Product/Prod [...] 6811144151

So far the pc comes out to be about $975 with out the psu. If someone could tell me what psu would be sufficient enough for this computer, I'm looking for a psu priced around $65. I was also thinking if the Hd 4870 was worth the extra $100 over the Hd 4850. I also have no intention of going crossfire since I will then have to add another $100 to the mobo price, and some more to the psu. Im intenter on using this pc for 4 years with a gpu upgrade in 2 years. Well for those 2 years i want to be able to play most games at decent frame rates with the exception of Crysis. Im also not intending to max out all the games, so im guessing I'll be able to. Well, drop your thoughts on my new build guys.

oh wait, i almost forgot, this is the monitor im getting, http://www.newegg.com/Product/Prod [...] 6824009094

id get the p45 neo board its $99.99 and look at the ocz 600w its got 4 12v rails and only $65 after rebates.

Im still not sure if i want a 4870 or a 4850 and CF later on.

oh and btw that monitor is junk. at best buy right now they have a 22" westing house with 3000 contrast ratio and 2ms response time for $249. alot better than 700 and 5ms

OCZ is supposed to be good.
Apevia makes some interesting cases, but the quality [control] was lacking in one I bought, and the materials were flimsy. On this one, I noted that it comes with an 80mm rear fan where it clearly accepts a 120mm; that's absurdly cheap.
I'd look at some of the low-mid priced CoolerMaster cases. I've had to re-tap mounting screws in them sometimes, but that's easy enough and I've otherwise been satisfied with them. They have good airflow, and come with and/or accept 120mm fans.

sorry to double post, but i was also wondering what would be a good fan for my cpu, since i plan on overclocking it. And can someone pls tell me if the hd 4870 is really that much better than the 4850.

Thanks Zip0p, well anyway is there anything else like thermal paste i need to buy seperately, or will it come with my cpu.
