Worth upgrading to HD 4890 with E6600 CPU?

Hi - after playing Arma 2 at 1400 x 900 with my current system (see sig) and most options on I have found a lot of mouse lag (and Crysis has to be run with pretty low options too) I want to buy a Sapphire Toxic HD 4890 Vapor-X.

Question is will this be worth it bareing in mind my current CPU? I don't have enough cash to buy a new MB & CPU at the moment.

Thanks.

Yes, it will be enough, your bottleneck is your 8800gts....

If you can overclock it to 3GHz, better

I would suggest saving some cash and getting a 1Gb HD4870 instead, it's a closer match to your CPU and resolution.
Agree with the overclock idea, my E6600/HD4870 combination yeilded useful speed improvements with a CPU overclock.
Just remember that both cards need two PCI-E connectors and most HD4890s need 1X6 pin and 1X8 pin, if your PSU is under 500Watts or lacks these connectors it might be a good idea to upgrade it as well.

Ok - well I bought the Sapphire HD 4890 Vapor-X (didn't go for Toxic as I messed up the price) never mind should be a good card to learn overclocking!

A great card, about to buy one myself. I wish I could find an 4890 Atomic but I haven't had any luck. They are factory overclocked to 1GHz out of the box. You could get the Vapor-X up to that as well but nice to know you have it for sure.

Standard fan or stock intel fans ate not so good for oc'ing.

You can get ~300-400 Mhz with them.

Room temps?

You have good chance of getting 600mhz OC.

Here it is 35c.

Hey guys - I have a related question!

Here are my specs:

E6600
Asus P5W DH
7900GT (3 years old!!)
4GB RAM
19" LCD

I am experiencing severe screen flickering during idle (just looking at desktop, running firefox - very light tasks) and terrible artifacts during gameplay. My graphics card is dying for sure.

Here's my question:

My GPU core temp is around 53C idle. When a game boots up, the temp jumps to 60C, and then I start to see artifacts.

Should I look into better cooling solutions? I also want to upgrade to an HD4890 - should I be worried about my computer temps with a more powerful GPU?

I'm going to pull out my GPU and give it a thorough cleaning. I hope this solves the flicker, but I really doubt it will If you guys have any idea about this screen flicker, any input would be greatly appreciated

Now he tell's me! Thanks anyway mate but I ordered the vapor-x 4890 a couple of day's ago.

Well forget the last question as it only came with one molex!

Got the card and am very happy, Crysis running at full tilt is excellent, Arma 2 the occasional stutter when viewing distance is maxed - but I think this game is badly made, the mouse smoothing sucks!
