I'm getting a new pc and i wanted to get some input/advice on the PSU. I need a PSU that will power my system and 2 8800 GTS in SLI. I'm not getting 2 cards right away, i will be buying 1 for now, but i would like to have an option of adding one in the future so thats why i need something to power 2 cards. Also i'm getting a power-hungry FX-62 processor which requires 125W as well. I am currently considering 2 PSUs: OCZ Game X Stream 850W or Enermax Infinity 720W My system specs: AMD Anthlon 64 FX-62 Windsor Asus M2N32-SLI Deluxe 2 GB of Corsair TWIN2X2048-6400C4PRO 2 8800 GTS 150 GB WD Raptor 250 GB Seagate Barracuda Zalman 9500 AM2 Lite-on SATA DVD Burner Mitsumi Floppy and card reader Creative X-FI Extreme Gamer Creative inspire P7800 speakers PS/2 Keyboard and mouse May also add an OEM SATA DVD-ROM Any thoughts on my PSU choices or recomendations for something better?
