Well I currently have a Dell Optiplex 745 SFF machine and am looking to upgrade the graphics card with a low profile GPU. Now what I am stuck on, is whether to go for the Nvidia GeForce GTS 450 or the ATI Radeon HD 5750 1GB, these both are low profile graphics cards and will fit in a SFF machine. Now what I am questioning, is which card would be the best investment, not only price wise (the Nvidia is roughly $20 cheaper), but performance wise. I mean I doubt either card will outperform its counterpart drastically, but I just want some input from this community. Also, my Optiplex currently has a 275W PSU, which is enough to run a HD 5570 low profile, but will it run any of these cards or will a PSU upgrade be necessary? From what I have heard from others, ATI has been known to be less "hoggish" in terms of power requirements than Nvidia, correct me if I am wrong.

Any advice would be appreciated, suggestions are welcome also!

Also, here is the link to the two GPU's for reference.

well, my recomendation is the 5750 Unless you want the 3dvision, because Im biased ATI. And you will need a major PSU upgrade for either card, the 450 requires a minimum 400 watt PSU and if I recall right hte 5750 is about the same.

Okay thanks for the input, I was leaning more towards the ATI myself, but was hesitant as I heard great things for both cards, a shame Sapphire doesn't jump on this and create their own version, always loved their cards. And I guess I can upgrade the PSU to 400W if necessary, they run as little as $25 if I am not wrong? Can you recommend me a specific cheaper end brand 400w PSU, I myself am thinking Antec or Rosewill?

Seems very few companies actually make low profile PSUs, but I think this one should work but make sure you get out a tape measure and check your dimensions before you order. As far as manufacturer goes, ya I feel ya my favorite is saphire as well, they make solid well performing cards. On the other note though, Powercolor cards do last awhile-they do seem to be missin a hair of performance from the saphire or ASUS brands, but I still have a old powercolor 1250 PCI card laying here on my desk thats like 5-6 years old, and it still functions perfectly. So at the very least, theyre long lasting.

I'll check out that PSU and my dimensions, and thank you for your input. Also, I have yet to have any of my sapphire cards fail on me :) never owned a Powercolor though.
