HELP! Onboard Vid vs. Old card vs. New Card vs. $$$ New Card, WHICH 1?

[joshuasp75]

So after researching a lot from the forums and reviews, I went ahead and bought most of the components for a completely new system yesterday (3/11) from newegg and will use what I already have as well.
I already have:
Case: 18.5"x17.5"x7.5" ATX Clear Acrylic Case
PSU: Corsair TX650W 650 Watt Power Supply
Burner: LG 22x? DVD Drive
Old Vid: Abit RX700 Pro-256PCIE w/ 256MB GDDR3 memory
Lots of various screws/cables/adapters/cards/fans etc.
The rest of my old system I plan on selling (mobo/cpu etc) so I won't list that stuff...

New stuff:
Mobo: Biostar Tforce TA790GX 128M w/ ATI Radeon HD 3300 onboard video
CPU: AMD Phenom II X3 720 Black AM3 2.8Ghz
Memory: 2x2Gigs OCZ DDR2 1066 PC2 8500 240-Pin
HDD: Western Digital 640GB Black SATA 3.0Gb/s OEM (hope it works!)
Cooler: Xigmatek HDT-S1283 120mm Rifle

So my question is for what video to use. I had planned on using the onboard vid until I could save up another couple hundred to buy a nice new card (I liked the Gigabyte GV-R485MC-1GI Radeon HD 4850 1Gb 256-bit GDDR3 PCIe 2.0 x16 for $170, since it has no fan and I like quiet). But newegg has a one day special, so I need advice quickly plz, on this card:
Powercolor AX3650 512MD2 Radeon HD 3650 512MB 128-bit GDDR2 PCIe 2.0 x16 for $40.
So should I just stick with the onboard video? or use my old X700? or buy the deal on the Radeon 3650? or just wait and buy the GB Radeon 4850?
I like to game, and have built this computer to try and update so that I can play any game on near or highest settings. I also want to know if I should get a new monitor to game on, but I also plan on hooking this system up to my 47" LG 1080p HDTV, could I just use that to game on?
Ok, so I might be forgetting some info, if I am just ask, but I want to go ahead and post this to get as much feedback today as possible, THANKS IN ADVANCE ALL!

Forgot to say that I hope to run Vista x64 on this system unless there is a problem or someone lets me know why that wouldn't work or is a bad idea, then I'll just use my old XP pro Operating system.

Just wait for another week or so. Prices will drop on HD4870 1GB and if you'll be able to get it in the $180 price range.

Is there a quiet or fanless version of the 4870? I really like a quiet system since when I'm not gaming I read a lot on my PC so fan noise gets really annoying (I remember going bonkers when I had a delta screamer back in the day to Overclock my old AMD). BTW the GB 4850 that I mentioned is $170 and has a $20 MIR until the end of the month so the final price is $150, also, the Powercolor has a $10 MIR so its final price would be just $30 shipped! Also, how long will the wait be for prices to drop? and how long with the price dropping last until it kinda plateaus and I should buy? I haven't followed vid cards and prices since I bought the 700 I have years ago.

So you're (Euphoria_MK) saying that I should nix going with either my old card or the cheap new one and just wait for prices to come down and use the onboard video?
I'll keep that HIS model that you mention below in mind and see what the price does...
What is the deal with the Accelero thing that you mentioned?

Also, what about a new monitor? Does anyone know of the viability of gaming on a HDTV like I mentioned? Just want to know if its possible and practical.

Yes I the HIS hd4870 1GB is very quiet.
I just checked the pricing on newegg and it went up to $224. I got it last week for $189.00 plus $10 rebate.
I think price will go down again.
The HIS 4870 1GB blue pcb, has a big heatsink with copper base and it keeps the temps on the card very controlled. Is not fanless but is much queter than anything else out there.
You can always spend an extra $36 and purcahse the Accelero Twin Turbo heatsink fan witch is even more quiet and it offers btter cooling. I purchased one myself since I am planing on ocing the card to 850MHz
