Hey everyone,
I want to upgrade my Radeon HD5450 512mb graphics card to something that works a lot better in video editing. I do video editing and sometime 3d rendering; I just can't stand the lag any longer. A bonus would be if I could run Skyrim in better graphics than everything on absolute lowest with tiny render distance.

I would like to keep the budget around $50. The biggest problem I have is that I only have a 300W PSU. I was thinking about the gt610 2gb or 620 1gb (both NVIDIA because of CUDA rendering and acceleration). Which one would you recommend? Any other cards you would recommend for my specs?

dont try the gt610 or gt620 they are crappy graphics cards(they would offer about the same performance as the hd 5450). try the AMD Radeon hd 7750 its a really good card that i think is the best graphics card that would work in your 300w psu.

It's hard to compare these low end cards because no one does benchmarks on them and there have been many different models sold under these names.
Here is the wikipedia page on the Geforce 600 series:
http://en.wikipedia.org/wiki/GeForce_600_Series

Many of these models sold as GT 610 or GT 620 are slower than your current card.
The 300W power supply suggests you might have an OEM system (HP or Lenovo), often the 16x PCI-E slot is not compatible with all graphics cards.
Is this an OEM machine?
What is your CPU?

Even if your graphics card update does work, you won't get much for $50.

Hey VincentP, what about the hd 7750. i pretty sure think that it works on all PCIe slots and should work in a 300w psu.

The HD 7750 is the fastest card from AMD that does not require an additional PCI-E power connector.
It does rely on the full 75W to be available from the 16x PCI-E slot, which is not always the case with OEM motherboards.
A 300W power supply may be enough for this card, depending on the +12V rating of the power supply and on which CPU is installed.

The Nvidia GTX 650 has similar performance to the HD 7750.
This card also needs the full 75W from the 16x PCI-E slot and does not require an additional power connector.
It would be a closer match to what they want because it supports CUDA.

Both these cards are over $100, well above the $50 budget.
The GT 630 is closer to the $50 budget.
The DDR3 version of this card starts from $54.95 on newegg and offers about 50% performance improvement on the HD 5450.
The newer version of the card has 384 CUDA cores.
This gives it more than 6 times the processing power of the HD 5450, but memory bandwidth is similar to the DDR3 version of the HD 5450.

The 2GB version of the same card for $59.99 has a $10 rebate available.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
I'm still concerned though about the motherboard compatibility.

The new model of the GT 640 DDR5 has a higher clock rate, but more importantly it has 3 times the memory bandwidth of the above card.
Gigabyte model for $79.99 on newegg.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
EVGA model for $89.99 on newegg but has a $20 rebate available.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Generally in this price range the AMD cards offer better value for money for gaming cards.
The HD 7750 is a very good entry level gaming card.
The poster however specifically wants CUDA support, so Nvidia is the only way to go.

Edit: I've updated the above a couple times as I've found different models of GT 630 and 640 available.

Thank you for all the info. You are right I have an OEM motherboard; it is the Foxconn (Bengal) RS780 and is part of my Gateway DX 4300-22 Desktop. The GT 630 2gb looks very interesting would it work on my Desktop? I was recently at Frys and saw this card on sale, but on the box it says it requires at minimum a 350W PSU and that's why I'm not sure it would work with my computer.I would also consider the GT640 DDR5 if it is much better than the GT 630 and will still work with my motherboard. I am not sure how to check motherboard compatibility. Will either of these cards work on my motherboard?

Your HD 5450 has a maximum power draw of 19.1W.
The GT 630 Rev.2 GDDR3 (with 384 CUDA cores) is rated at 25W.
You can tell if this is the right GT 630 because the number of CUDA cores should be written on the box and on any website selling the card.
The older GT 630 cards are not as good and use more power.
The power available on the 16x PCI-E slot seems to be the main reason people give for incompatibility with these motherboards.
If that is true, this card should work fine.

The newer GT 640 GDDR5 is rated at 49 W.
The specification on the box should show if this is the GDDR5 version.
Again this is well under the 75W specification of the 16x PCI-E slot.
It should work, and the additional memory bandwidth would make a big difference in performance.

Either of these cards should work, but unfortunately there are no guarantees with OEM motherboards.
For a normal retail motherboard, if they find some incompatibility with a newer card they tenbd to issue a BIOS update.
The OEM may not bother because they aren't selling the newer cards for their machine.
It is definitely worth updating your BIOS version to the latest available before upgrading the card.
You won't harm anything by trying the new card if by chance it doesn't work.

now the gtx 750 ti is the best


Still no CUDA support, as was specified as a requirement in the original post.
Edit: Sorry, that isn't true. Yes, the gtx 750 Ti is the fastest card now available not requiring an auxiliary power connection and it supports CUDA. Well outside of the $50 budget though.

Just as a follow up I ended up buying the "ASUS GT630-SL-2GD3-L GeForce GT 630 2GB 64-Bit GDDR3 PCI Express 2.0 Low Profile Ready Video Card" from newegg (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) and am very happy with it. It works with my 300W psu and I was able to preview the video in my video editing software in 1080p (also able to play skyrim at high).
