Hi all,

I know, I know - yet another similar thread!! hehe

Im tempted to buy a 4850 today & from what Ive seen its worth the jump but I want to chk if you think my X2 4800+ would be a bottleneck with this card? I can clock this to about 2.6 max. My screen runs at 1680x1050.

Also, will my Corsair HX520 power supply be ok to run the 4850?
 
I think that seems a good move. At 2.6Ghz and at 1680x1050 would see the benefit most surely but is there any games that are struggling for you just now to warrant the change?.
 
You will see the biggest gains when using a lot of AA and AF...your CPU is a bottleneck but is still plenty sufficient...and your PSU is fine too.

I say go for it...

I don't really have anything that I would classify as 'problems' but with Crysis it does lag a little from time to time. I play mostly GRID at the moment and that runs well on the 8800GT.

Im just thinking I may get more for the 8800 now and the 4850s are a very good price so looks like its a goer!

thanks..

Crysis actually runs a little better on Nvidia cards so the jump might not be as impressive as you hope in that game. All others should be though :).

Good luck with your new card.
 
cheers, just placed the order & at £99.00 ex VAT once I sell my 8800GT I cant complain, even if the difference isn't huge.. :cool:
 
whilst i agree with your card choice
i went from an 8800GT to my 9800GTX which is oveclocked well past the factory overclock

so similar performance to a 4850

but recently i upgraded from my 4800+ @2.8GHz [2.5GHz@stock]
to a new motherboard running a e6300 intel chip
i was going to use this as a stopgap
buth the intel is @ 3GHz [1.86GHz@stock]
a way bigger overclock
and much higher benchmark scores than the amd

i would suggest perhaps sticking with the 8800gt and changing to an intel chip

my motherboard was £100 and my chip came form the members market here for £25

so it cost me less than a graphics card and the performance increase was massive compared to my 8800gt>9800gtx move

thanks for that. U may well have the right idea but I have plans early next year to build a complete new system so wanted to hold off on the motherboard & cpu for a bit. If Im honest I dont really need a new graphics card but sometimes you just gotta treat yourself!
 
i know what you mean
- however the gains from an upgrade from 8800gt > 4850 @ £120
wouldnt be as noticable as an upgrade to maybe this spec

p5q
and a second hand e6600 or a new e2200 which would easily do 3GHz

fair enough, maybe I shouldn't have hit that buy button so fast! oh well... :rolleyes:

I wouldn't worry. My LCD was 1680x1050 and my X2 @ 2.8Ghz ran very well with the 8800GTX. Only 1gb of DDR also in my last machine and games were fine. I actually feel that I didn't gain much from moving to this machine (gaming). Maybe try and push for a little more on that CPU :) but 2.6Ghz will be a great starting point.
 
Well, just to give an update if anyone is interested - I got the HD4850 to replace my 8800GT and am quite disappointed tbh.

I didn't expect much of an improvement but I really didn't expect it to be worse than the 8800GT. I'm not into measuring frame rates (not really that kind of gamer) so am more interested in how games feel so COD4 plays more or less the same as with the 8800GT.

My biggest disappointment is however GRID. This played perfectly on the 8800GT but with the 4850 it tends to stutter a bit, especially on the menu screens & occasionally during play. I read a little about audio drivers causing issues and I deleted hardware settings files (as advised on Codemasters forum) etc.. still not great.

Any ideas?

Cod4 should play better, simply because you switched to ATI and reports are saying the cards perform a lot better.

Which 4850 did you get? Also have you tried overclocking it? Should easily get to what is in my sig.

Other than that, make sure you un-installed all previous drivers, including nvidia ones, and used driver sweep. Then try the 8.7's or 8.8's and see how it goes.
 
I'm did un-install all nvidia drivers but didnt use driver sweep - might be worth a try. It was the Gainward HD4850

I'm currently using 8.8's and havent tried overcloking it yet. Might give it a go later.

Also look into configuring the xml for higher fan speeds so your card doesn't overheat..

Just out of interest can you list your pc specs again?
 
dmx07 said:
I did actually do that fan tweak and set it at 40% as far as I remember (or maybe 50%...)

XP Pro
AMD Athlon 64 X2 4800+
Asus A8N SLI Deluxe
Corsair HX520
2Gb Corsair Value
HD4850

Yer I have myn at 45% and it does alright, sometimes need it as high as 50% to keep it down when overclocked. Specs look good, can't think of why there is no performance increase, other than a conflict of drivers as stated above.

Have you got v-sync enabled? Try it with it off.

I never use v-sync so that's not the issue, maybe I should try turning it on! I have a feeling that it might be an audio driver issue as I did have some trouble with sound when I installed the 4850 initially. Might investigate more this evening.

ah, that sounds like the problem then. I've had numerous problems on all of my pc's with onboard sound. If you're using that try using the hdmi out port on that card. Or get a new seperate sound card.

Remeber to completely clean out all drivers each time you re-install them.
