How much of a performance boost will/should I see here?

[DarkstarOne]

I have a Dell PC with the stock 360W PSU and Radeon 4850 video card.

It's being replaced with a Coolermaster 500W PSU and a Radeon 6750 video card.

How much of a performance boost in 3-D gaming should I see with the 6750?

The 4850 is the exact same as the 5750.You won't see much,if any,performance increase.The only difference between them is that the 6750 has DX11 support.

What is your budget and maybe we can help you find something better.

What are your full system specs?(CPU,RAM,etc.)

The upgrade is being performed for free (warranty service, the PSU and video card bought the farm), so I wasn't going to argue about it.

I'd be into upgrading the video card further, but my budget is limited for that to about $100-125...could stretch a TOUCH more possibly if it were really worth it. What's the best card I can get in that range that the 500W PSU can handle?

The system is a Dell 435MT, 6GB RAM, 750GB HD, one multi-drive (CD/DVD reader/writer)

What type of CPU do you have?

I'd say the best option for you would be to go with the 6850.The 6850 will be a little outside your set budget but it's well worth the extra money.The 6850 it almost twice as powerful as the 4850/6750.

My CPU is a i7-920.

The card looks good, but it's a touch outside my price range, when you figure in taxes and shipping.

What's the best I can do in my price limitations?

The best you could do within your budget range would be a 5770.But it's not exactly a huge step up from a 4850.That's why I think a 6850 would be a better choice.

5770

Actually after looking at TigerDirect I think I may have found a 6850 in your price range but theirs a catch.It has a MIR.

@ OP, you didn't mention anything about your gaming resolution.
I saw in the original post that you said 3D, are you going to play 3D gaming ?
If so, none of the mentioned cards will serve you well, and some of them are not 3D capable.

And the 5750/70 performs much better than HD 4850, GDDR5 is generally faster than GDDR3, but as said above not a huge performance... it's like 20% gain.

I didn't mean 3D as in 3D with glasses.
