Is the Radeon HD 4850 right for my rig?

Hey all,

I'm no tech expert, but I like to keep up with the latest PC games, like Dragon Age and Left 4 Dead 2. I am frustrated right now by my inability to see the rain effects in L4D2 without serious slow-down, so I'm thinking about upgrading the graphics card.

I am drawn to the Radeon HD 4850 because of the February 2010 buyer's guide. But I don't really know if it's the right choice for me, as I wonder how much my PC is going to bottleneck my options. Here is what I'm currently working with:

- Pentium® D Processor 940 with Dual Core Technology (3.2GHz, 800FSB)
- 2GB Dual Channel DDR2 SDRAM at 533MHz (4x512M)
- ATI All-in-Wonder X1900 (256 MB GDDR3)
- 480W Power Supply (purchased for the sake of the X1900)

So what do you think? Could I go with the HD 4850? And if so, should I stick with the 512MB or spring for 1GB?

Thanks for your help!!

P.S. I know my PC is lame...I bought it in June 2006, so it's coming up on 4 years now. Actually, I'm a little surprised it's still rolling along like it is.

As you've already proven, you WILL have some bad bottlenecking issues. The HD4850 is great for L4D2, but not so much for your processor. There comes a point where upgrading the graphics card, "Just isn't enough."

Yes, u can go with 4850 but upgrade your CPU first, u can't max out the card's performance with that pent.D. :)

Darn, I kind of suspected as much, but I really appreciate you guys chiming in with advice. You wouldn't happen to have any CPU recommendations...?

You'll need a new MOBO/CPU/RAM, though.

785G: $70
phenom II x3 720: $105
2x1GB DDR2 Dual-Channel 1066: $45
HD4850: $90.

Even without upgrading your CPU you will still see a large performance increase. Not so much as if you had new CPU obviously, but if you know that you will be upgrading soon enough then it makes sense. Depending on what resolution you will be playing at is the deciding factor on whether or not you should go for a 512mb or 1GB card.

:fou:  Not sure i agree with the above due to the fact the pci ex for the hd4850 is a 2.0 expres slot and also the cpu is probably the case i recomemd starting from the beggining in building a new computer.... thats will stand the test of time.....
cpu= intel i5 750 £141
motherbourd= GA-P55A-UD3 £109
ram= 4gb g-skill ripjaws 1600mz £90
grahics= ati radeon hd 1gb 4850 £87
This makes a fat system at minimal cost and will stand the test of time also possible to put 2x hd4850 cards in using the X-Fire creating a massive 2gb graphics.... has great overclocking potential has well no game on the market will test this system...

When you crossfire or SLi cards the memory amount isn't added together

E.g... 2 x 4850 1GB's in crossfire still only leaves you with 1GB Video memory (Although thats plently)

@OP if you can tell us your budget then we can recommend a suitable upgrade
