PSU Question

[schumi]

Hi I currently have a 8800GT and a Antec 550w modular PSU and am wondering whether to upgrade to a new GTX280.
Would i need a new PSU ?

MY PC setup is:

Intel Core 2 Duo E6600 @ 3.2Mhz
Gigabyte GA_965P_DS3 (Socket 775) PCI-Express DDR2 Motherboard
4GB OCZ PC2-6400 Dual Channel Platinum Revision 2 XTC Series DDR2
BFG GeForce 8800 GT OC 512MB GDDR3 HDTV/Dual DVI (PCI-Express)
Creative SoundBlaster X-Fi Xtreme Gamer Sound Card UK Retail
Western Digital Raptor 36GB
3 x 250GB Sata HDDs
Antec NeoHE 550W Modular ATX2.0 PSU

Yeah i think the Antec is 18A on the 12V rails so i guess i will need a new psu, anyone got any suggestions for a new PSU.
Also what do you guys think about the performance increase from a 8800gt would it be worth it ??
I'm currently playing Age of Conan and find it a bit sluggish running at 1680x1050.

So i should be fine then looking at those stats thx

Now i just have to decide whether to get a GTX280 or not

connectors required

Hi, i have been holding off on a gtx280 waiting to see what the ati 4870 was going to be like and it looks like its a much better option that the gtx280 however i am uncertain about the power connectors required for the card.
My PSU has 2x 6pin PCI-e connectors are these sufficient ?
also do you think i will get any benefit upgrading from a 8800GT to a 4870 ?

thx
