Hello,

Yesterday my old graphic card (Gigabyte 4670 512mb 128bit) stopped working for no reason. Luckly I still had warranty so I went to the store and now I need to get a new one.

My choices are:
Gigabyte HD4850 512mb 256bit
Sapphire 5670 1gb 128bit

I know there's a big performance difference between the two cards but bear with me.

My PC is composed of:

Intel e5200 @ 3.3 ghz
2x2 GB RAM 800 MHZ
Samsung 750 GB HDD
RAIDMAX RX-420BK PSU

OK so my question is:

Will the PSU run the 4850?

I read a few reviews here and there and it seems that a whole PC with the 4850 graphic card would eat up to 260 w in full load...I'm not sure of that because some reviews said that a PC with a 5670 card would eat up to 230 w in full power. I know this doesn't seem real cuz the 5670 is a much weaker card...

So what do you think?

Thank you !

amd says 450w minimum, if it does run it i think you'd be pushing it a bit too hard.

So I'd be better off with the 5670? Or my PSU won't run it...

Here are my PSU specs:

+3.3v-20A,+5v-26A,+12v(1)-14A,+12V(2)-10A,-5V-0.5A,-12V-0.8A,+5VSB-2A. Double Rail 12V + Active PFC

Ask if you can pay a "small fee" to upgrade from the HD 5670 to the HD 5750.

The HD 5750 basically has the same performance as the HD 4850 (actually a couple of % slower) and consumes a little more than half the power of the HD 4850. I think under typicalgaming conditions thats 66w vs. 120w.

Here the 5750 is like 200$
My 4670 is around 120$
5670 is like 140$
The extra 80$ is a lot for me at least...

If you can afford a Humvee, yeah the roads are great !

Also to get to that "fantastic road" on which that Top Gear episode was filmed you need a helicopter.

what about a 9800gt (the green edition) or a gts450?

i think the 5670 would still be a good upgrade to the 4670. you could wait for the 6000 series though, rumoured to have better watt-performance ratio.

I prefer an ATI, I think I'll go for the 5670...it's at least 15% faster than 4670, direct x 11 gaming will suck but usually life sucks.

could depend on what resolution you play at.

according to 3dmark vantage its nearly twice as powerful as the 4670.



in dirt 2, you could play dx11 @1280x1024 pretty well.

It was kind of lucky that they had one on hand then. ;)  That's enough OT, I'm out.

I play at 1680x1050, the only 4770 available is Gigabyte ATI Radeon HD 4770, PCI-E, 1GB, 128 bit, GDDR5 which is 10$ cheaper than the 5750, still out of my price range.
For now I'll stay with 5670 and in the future go for a better PSU and better graphic card

well you will still be looking at a good performance increase anyway. the 4770 is better but just get what you can. this shows results from the old drivers so it could end up being faster.



nearly double the fps in fallout 3.

Ok, thought well and I think I'll go with the 4850 and if my PSU won't be enough I'll buy a new 550w PSU.

What's the worst thing that could happen if I test 4850 on my current 420w PSU? Could the PSU blow up? Or worst the GPU ?

The 5750 is too expensive I prefer buying the 4850 and a decent PSU

you would still end up with similar performance in the end, except without directx11 and higher power usage.

I've got 2 choices now

Gigabyte 4850 512mb + Fortron SAGA II 500w PSU
or
Gigabyte 5750 1gb

What should I take? Both options are about the same price ~200$
October 3, 2010 11:08:59 AM

I can't buy the graphic card anywhere else than my local store cuz my old 4670 blew up and it's in waranty so I only have to give the difference between which card I want and my old 4670 and the prices are a 10% higher than on a online shop.

My old 4670 was 115$ 2 years ago, 4850 is 125$ and a 5750 is 200$. I have only 80$ to spare so it's 4850 + PSU or only 5750, but I think 5750 would work on my 420w PSU it has 24A on 12v

I'm not sure if someone here is still considering the 5670, but I was looking at getting one (and eventually did) and during my research I found out that the 1GB version and the 512MB version perform almost identically in most situations; http://www.legitreviews.com/article/1187/1/

I'm only running 1440x900, but with AAx8 and detail setting at Very High, Batman:AA runs smoothly.

5750 is much faster than the 5670, at least in DX11 5670 is failing, I'm not planing to use DX11 but overall 5750 is better. In the link you posted 5750 is at least 50% faster in every test...so now I'm more enthusiastic about the 5750. But if my PSU can run it...that's another story.IMO it should.
October 3, 2010 1:06:19 PM

5770 is 40$ more than 5750 , that's too much for me

running a 5770 requires a minimum of 24A. i have also seen people state that the green edition of the gts250 requires a minimum of 24A aswell. the gts250 performs similarly to the 5750 and 4850.
October 3, 2010 1:37:45 PM

I have a 24A PSU (12v1 14A, 12v2 10A), I have a friend that runs 5750 on 6 year old no-name 320w PSU with 17 A on 12v (one rail) and played games like Metro 2033 on high settings without any problems. I guess my PSU can run the 5750 just fine...
October 3, 2010 2:53:49 PM

OK :D  Thanks !

So between 5670 and 4850 I'll go for the 5750 :D  Thank you all for your support !

i thought he meant to check prices of the gts250/gt240/gts450. the original poster stated he prefers ATI.
