Seems like 4850 having heat issue. It's either wait for a better revision or change the reference cooler with a better one. Anyway is there plan for a 4850x2?

If GDDR5, then it should be HD4870 then? I saw the comparison of HD4850 and HD4870 difference is the RAM if not mistaken. Correct me if im wrong though

I was wondering if ATi graphics cards are having this problem similarly to NVidia whereby the automatic fan control fux up. Using RivaTuner to automatically set the fan speed, it will reset it to 25% no matter how i tried and hence that prevent any overclocking. Unless with a 3rd party cooler.

Hopefully AMD can deliver again with the best bang for buck pwnate 4850x2 .. But i doubt it. Haiz.. gonna wait again

Emm.. not to be confused but i understand that 4850x2 and 4850X2 CF is both different right? Whereby 4850x2 is a single card actually CFed without requiring a mobo with CF functionality?

I hope we can expect to see 4850x2 to be around RM800+. Ah but i don't think that's possible.

Thanks for the confirmation . I was wondering... the following which is better?

1 single card HD4850X2
2 cards Cross-Fired HD4850

So is a single card HD4850X2 better or 2 HD4850 card crossed-fired?

Thanks

If not mistaken my mobo should be PCIe 2.0 just no CF or SLI functionality. Damn if need to change mobo again

I'm currently using PSU Enermax FMA-II 460W 32A dual 12v rails. Was wondering if it's enough for HD4850 or HD4850X2? Hopefully i don't have to change PSU soon

Are you sure? I thought requirement for HD4850 only 450W? Em actually what happen if i don't change the PSU? I'll get artifacts or something? Also, anyway to check my PCIe is v1.0 or v2.0? I check my mobo website on the specific model but it didn't mention PCIe 2.0 or 1.0 just PCI Express X16 slot.

Thanks alot Kytz. Then i guess it will not be enough for HD4850X2 then. Maybe i'll just grab myself a HD4850 or HD4870 at max. And probably change to another rig for higher end gc

My gosh RM1.4K for 4850X2? .. I buy 2 HD4850 CF also no need RM1.4K

Anyway not sure the pricing here in m'sia yet. If too high it won't be worth for X2.

Glad that someone asked the difference between PCIe 1.1 vs. PCIe 2.0. Since there's not much performance gained, then it won't make much sense to upgrade my mobo

How can i know or how do i check whether my mobo or my cpu is bottlenecking or limiting the GPU performance? Any software to check that?

Thanks for the reply. But 3D Mark scores comprises of many factors such as what model of mobo, gc, cpu, ram, psu, hard disk, etc. It might be either one that is limiting the 3dmark score . If both AMD X2 5200 and Intel E6550 has identical components, only differences are the CPU and mobo then i guess it will be much easier to isolate whether the cpu or mobo is limiting the GPU

Anyway it would be kind of a big hassle to check if mobo/cpu is limiting the GPU if only one can compare with someone with similar setup.

I thought for ATi cards Sapphire/HIS/Powercolor are one of those of better quality? I saw on some seller thread mentioning that's why the price are more expansive

Hmm.. i saw a thread on HD4850 by coolice. Gainward HD4850 watercooled but the OC is not impressive. Yields only additional 1-2FPS in Crysis at max. OC

Well reason why PC gaming is dying and developers are moving to consoles because pirates are killing them.

DirectX 11? Geez.. Micro$oft sure knows how to squeeze $$ only. I guess the DirectX 10 has not been maturize yet as not many PC games on DX10 yet.

Emm why not? If DX11 has so huge an improvement over DX10 and supporting multi-cores processor, i guess it should boost the sales of Vista. I guess it's good for the giants since there's always on-going business for the GC manufacturers.

..Then DX11 will be Windows 7 exclusive.. no DX11 for Vista/XP .. Well they still make more bucks

In that case it's better off getting a 3rd party cooler . But i've seen coolice 4850 overclocking the result not impressive. Max. OC only gains 1-2FPS in Crysis
