Advice on adding a video card to old dell optiplex 745

I am trying to figure out if it would be worth adding a video card to an old computer. I want to be able to play recent titles (ex. Battlefield 3) at low to medium detail settings and no AA at modest resolutions (1680x1050) but don't want to spend more than $75 on the card.

Is there any card that I can buy which will let me do this. I am willing to buy a used card from anywhere (ex. craigslist, ebay). I was looking at a Radeon 3870 for $35 or a Radeon 4850 for $50.

Here are the system specs:
Intel Core 2 Duo 2.13GHz
2GB RAM (Upgradable to 4GB)
280W PSU (No PCIe connectors)
250 GB Hard Drive

    Your goals are unrealistic considering your budget. Buying used cards is a complete crap shoot. In my experience it's usually not worthwhile since there's a good chance the card will be DOA. I've actually purchased a card that was "tested and working" and when it arrived it clearly had toasted/leaking capacitors (which I would have seen had I looked closely at the listing photos). I've had similar experiences with two other cards.

    If you're certain that the 4850 is in good working order it's not a bad deal at all, but it does require a single 6 pin PCIe power connection. If I were you though I'd up my budget a big and just get a brand new AMD Radeon HD 6670 which is the best card you can get without using a 6-pin power connector and it offers performance nearly equivalent to the 4850 you list.

    EDIT: Asus HD 6670 with GDDR5 memory that's in your budget....
  2. Plus an old PSU that says "280W" may not have enough 12V power available. The unit would need to provide almost all of that power in 12V form, and that is unlikely with a generic PSU.

    If anything would work the newer 6670 would be most likely, as the power demands should be much lower.
  3. It doesnt really matter what card you get, since you dont meet the minimum cpu requirement. It is 2.4Ghz for a core2duo processor, yours is 2.13. If you can get it to run, it wont be medium, and it wont be at 1680X1050 either
  4. Thank you folks. Looks like that computer is going to be used for web browsing by my parents.
