I'm looking to upgrade the video card on my desktop, and while I've done this in the past with prior computers I always just kinda "winged it" and lucked out. I did a bit of researching and was wondering if any of you hardware buffs might be able to confirm my findings, or steer me in the wrong direction if I'm wrong.
I should say that I'm not a PC gamer, nor do I want to be; my goal is simply to upgrade from my onboard ATI Radeon HD 4200 to something that has dual DVI outputs. My onboard video card supports my dual monitor setup, but only by having one plugged in via DVI and the other plugged in via VGA.
My desktop is an HP p6531p (link), with what looks like a 250W power supply. I'm finding most video cards, such as the EVGA GeForce GTX 550 Ti (link) require 400-500W power supplies, which means I'll have to upgrade that as well.
Knowing nothing about power supplies, I did find a forum post online (link) of someone with my same desktop who did upgrade his power supply to a OCZ ModXStream-Pro 500W power supply (link), so I'll probably just go with this since I know it works.
So here are my questions:
1) Is there any reason the OCZ ModXStream-Pro 500W power supply might not be the right choice? They offer 600W and 700W versions as well; is there any real reason for me to spend the extra for one of these?
2) The EVGA GeForce GTX 550 Ti looks like it's what I think they consider a "dual slot" video card, meaning it will take up the room of two cards in the case, even though there is just the one slot plugging into the motherboard. Right?
3) Does anyone have any recommendations for a non-dual slot video card that will support dual DVI outputs, just in case for some reason I discover my case doesn't have the room for a dual slot video card?
In my opinion, just get anything that's cheaper for you. They are not different in qualities and they are from trusted brands. The seasonic one is the best though, but most expensive, if you can get it I recommend it.
I do not recommend 550 ti because it's bad by price-to-performance. You can get much cheaper 6770 which delivers almost the same performance, here:
Dual slot card means it take 2 spaces of PCI brackets in the back of your case, usually covers another PCI slots and therefore cards can't be placed there and also need bigger space. Just note that, otherwise it's fine my friend .
If you are looking for a single slot card that are as fast as 6770/550 ti, you may wait to the stocking of the 7750, it's a single-slot card with HDMI, Dual Link DVI and DP. They are out not long ago and should be stocked near times .
