Buy a second 3870, or...?

Here's my dilemma...I built a little while ago, a budget pc for around $700. I have a 4 gigs of ram, a x2 5400+ in a MB that supports crossfire, so I bought a 3870 for around $150. Now, as the 4800 series release is drawing nigh, I am wondering if I should just go ahead and buy another 3870 for another $150, or just wait until they come out and buy a new card. I will not go out and spend $300-500 on a new card, but I would like to perform a cost-effective bump up in the graphics department.

Thanks

to be honest with the X2 5400+ and a Crossfire 3870s you might/probably will hit a bottleneck and only see maybe a small increase in performance.

Also Crossfire/SLI you normally only see the performance boost in higher resolutions. However now some games have a higher need for more power even in the lower resolutions.

My MB supports PCI-express 2.0 x16 for one card, and x8 each for crossfire mode...

What would be my best bet to remedy the situation? Wait for the 4800s to arrive? Get a 6400+?

best choice would be to overclock your processor and then wait around and see how well 4870 performs and if it's worth getting. right now we're only getting specs and speculation. i'd wait for the reviews. don't get a new processor, just overclock what you have right now. once benches comes out, decide crossfire or new card.

don't forget what fatfunkey said about the resolutions. crossfire will see great improvements in higher resolutions, so if you play in like 1280 x 800 or 1600x1050, you are better off with a single faster card. any higher resolution would benefit from two cards.

You could always get a 4850 an oc it a little. You wont run into scaling issues (as you would at some point with crossfire, particularly if your gaming at less than 1600x1200) and you could ebay the 3870. In like 6 months the 4850s will be alot cheaper and you could get a second one for that crossfire mobo. I wouldn't worry about your cpu, your gpu more or less is your gaming performance as a golden rule of thumb, and ive seen a couple of benchmarks recently that back that up quite comprehensively.

What about the possibility of using crossfireX with the 48x0 and the 3870? food for thought.

i don't think that you can do that yet. to crossfire, the chips needs to be the same. like they are in 3870 and 3850. crossfirig these works. but i doubt that you can get the combo that you asked for.

I have the same issue, I just built a new system(see my sig). I was wondering if i should get a second 3870. I play at 1200x900 so i guess it wouldnt help.

I am disappointed with the performance of the 3870 anyways.

Would it be better to forget xfire and get a nice upper/midrange nvidia; 8800GTS (G92), 9800GTX, GTX2xx? Then ebay my 3870.

If you play such low resolution isn't a 3870 good enough? It should do fine upto 1600x1200 resolution no problems.

What are you guys playing that need more power than a 3870 for such low resolution? Crysis? A moot point once you finish the game.

I want to resurect this thread.

I have found a 3870 for $129. It is exactly the same card i have.

As cheap as that is, is it worth getting a second card.
