My build AMD/Gigabyte 780 G/Radeon/mid end computer

So I found these gpu online and I don't understand what the difference is since they all read 512 mb (I thought that was the important part!)

Radeon 3650 - 4890 all 512 mb

I know a lot of different brands make them, but really what is the difference between these two for example;

And what does PCI express mean? I notice those words appear by the cheaper graphics cards.

Thanks you guy!

PCI Express is the bus that it runs on or plugs into. Like PCI, AGP, PCI-e. The main difference is that the 4890 is a really fast high-end gaming card and the other is a mainstream I guess "HD Content" card. The 3650 won't game very well.Please google first, or read some posts or threads in these forums, they can be very helpful. Oh and also the 3650 is almost 100 dollars cheaper.

AKM, I have been reading several threads and checking on notebookcheck.com but there is so much information, it is hard to get a specific question answered, it is like info overload.

And for the Sims 3, which plays it better, and like I said they both say 512 mb.

The 3450 you linked is not really a gaming card. It's too slow... although some simple or older games would probably be OK. Speed is the most important thing, not memory.

The 4850 you linked is more than enough for the Sims 3. If that is ALL you want the card for, and you won't be playing any more demanding games, then you could get by with a 4670 easily:

I linked the HIS version of the 4670 because of it's superior cooling and quiet operation.

Now, if you are also playing Call of Duty 4 and World of Warcraft, then you need the 4850 or more.

Your 780G motherboard has built in HD 3200 graphics chip.
The $53 HD 3450 you linked is a very poor value upgrade.

If you'll still be using a 1280x1024 resolution monitor a 4650 or 4670 is a good match and a relative bargain.

The 512Mb memory isn't just the main factor of the cards performance. Yes the 3650 and 4890 have the same memory, but there are other specifications which make the 4890 massively better than the 3650. Just goto the NVidia website and check the specifications of each of those cards. The 4890 is a high end graphic card, the 3650 is a low end graphic card, if you have the money get the 4890.

I just noticed your post in the graphics section and you seem concerned because the 4830 and 4650/4670 aren't listed on the Sims3 box?

Not to worry - with the 2400, 3450 and Intel GMA 3 & 4 also on the list the 4830 & 4650/4670 series are still good choices.

For the Sims3 and 1280x1024 resolution I think 4870/4890 fall in the "massive overkill" area of an low budget build.

He means ATI. Go to the ATI site for info on these GPU's.
And although memory is 1 important factor when comparing video cards, it is a secondary concern. More memory means you can run at higher resolutions, and generally turn detail levels up higher. BUT you have to have a card that is built powerful enough to use the memory. Several of the cards listed in this thread are very powerful cards indeed, and some are actually not meant as game playing cards at all.
Go here and breeze over this chart to see how all the cards fit as far as who is who.

You should read the whole article, it is from the front page of Toms, called "Best Graphic Cards for the Money", and is updated monthly.
Gives advice on everything from modest budget to full blown top level gaming cards. Definetly worth the read.
