I'm assuming that all of these will cover adjoining slot, but if one doesn't, let me know since very vew slots are available. Primary focus is performance for Photoshop and Lightroom. I don't game. Will use 2 monitors. I don't need the absolute best but want something that will handle upgrades to LR 3 and PS CS5, e.g.
Thanks for help!
APPROXIMATE PURCHASE DATE: Now!
USAGE FROM MOST TO LEAST IMPORTANT: Photo editing and printing (Adobe Lightroom 2.0, Photoshop CS3); web design (Dreamweaver); page layout (InDesign); recording video to disk (occasionally) gaming not a concern
CURRENT GPU AND POWER SUPPLY: 450 watt [can swap in a 500 w ps from old system]
OTHER RELEVANT SYSTEM SPECS: HP 380T (same motherboard as prebuilt 270f)
PARTS PREFERENCES: Have used nVidia in past but either is fine
adobe lightroom does not have demanding graphic specs. I've never used it but I have read that Nvidia works better with it. Although they never state why and it could just be simple product loyalty. The ATI 5450 is more then enough for your needs, as are the two Nvidia cards.
