Good Idea to Upgrade to HD 6850?

post #1 of 12
Thread Starter 
Would upgrading from my hd4850 to a 6850 be a good idea for gaming at 1920x1080? Is the 6870 really worth the extra cost?
post #2 of 12
at that res i think a 6950 would be a better option bc of it will perform a good amount better than the 6850. if 6950 is too expensive then id look for a 560ti or a 6870.

You think the extra cash is worth the 6870 over 6850?

The 6850 overclocks very well and will get fps over 30 in just about every game (including Crysis/Warhead) at that resolution. I've not tried Metro 2033 maxed out, but the lowest I've ever seen my fps in Crysis was 28 during some of the most intensive areas (while overclocked). Generally it's 35-45.

If you want more than that then you're going to need either a 6950 or a GTX 560 Ti. The 6870 does perform better, but doesn't overclock quite as well. In my opinion, because of that, it's not great value for money.

My friend has two 4850's in crossfire, and he usually gets about 5-10% more fps than I do with my 6850. I imagine you can find them cheap second hand now and it'd be cheaper than a new 6850. Having said that, your motherboard probably wouldn't support it. I can't find its specs anywhere, but it ought to have at least a PCI-Express 2.0 x8/x8 split.

My MB can do 8x/8x crossfire, but I'm not sure 4850 CF is the best option. Although it would be cheaper, but i thought it might be worth more to put that money towards an entirely new card.

How far can a 6870 OC over a 6850 OC?

If you're looking at a 6870 then go for the B.E. version. They're very close to a 6950 performance and about $40+ cheaper, around $215-$225. Though 6850 CF would also be also be a great choice since HIS offer them for $144 each AMR.

Can't you just OC the 6870 rather than getting a BE?

Well, here are the benefits of each:

4850 Crossfire:
- Cheaper.
- Faster.
- can split them off into two secondary machines when you move on.

6850:
- Single card means no CF Issues.
(not a big issue nowadays, but still an issue with newer games that AMD hasn't had the time to adjust the drivers for / any game you play in windowed mode)
- Can add a second 6850 later for cheapness.
(Although by this logic, you still ought to go with the 4850)
- Lower power draw
- Lower number of PCIe power cables required.
- Less space taken up inside the PC.
(Which will mean that it shouldn't get as hot)
- Directx11 support
- New technology comes with new warranties

I can't think of many more, but my point is that the cheaper and the faster tend to be what most people want. If the others (especially Dx11) bother you, then consider the 6850. If not, the 2x4850 will be about as fast as a 6870 (maybe a touch faster, but we'd probably be talking in the region of 1-3%).


Why do you want a new card? Depending on the prices I could find a 4850, I'd probably crossfire it. That is, if my PSU could handle it. Yours should handle it easily, I think.
