New Graphics Card (replacing integrated)

Snip from link i posted regarding test system

Our test system is based on a power hungry Core i7 965 / X58 system. This setup is overclocked to 3.75 GHz. Next to that we have energy saving functions disabled for this motherboard and processor (to ensure consistent benchmark results). On average we are using roughly 50 to 100 Watts more than a standard PC due to higher CPU clock settings, water-cooling, additional cold cathode lights etc.


Based on a 7750 and your current setup you should be fine, but i wouldnt overclock anything, just to be safe.

Ah thank you.

from the link Nickolp1974 posted:

Measured power consumption R7750

System in IDLE = 155W
System Wattage with GPU in FULL Stress = 188W
Difference (GPU load) = 33W
Add average IDLE wattage ~10W
Subjective obtained GPU power consumption = ~ 43 Watts

I have 250 watts for the PSU, is that going to be enough?

Your PC would draw less than the above system, so yes, you'll be fine on a 250w PSU. You could always check your PSU to see what amperage it offers on the 12v rail (Check for any lables)

:( Not what I was hoping to hear.

I am going to get a new PC in 6-7 months, no chance of getting it any sooner.

Low/medium settings would be fine for me, there must be something I can do mean time?

For GW2, I think I can give you some advice on it, considering I game on it on both my main PC with i5 overclocked 2500K system with a 5850, and my secondary PC overclocked E5200 (effectively a Core2Duo E8xxx CPU with less cache) system with a 9800GTX+.

One thing I have to make very clear is that without a i5/i7 system, there's NO WAY to make the minimum frame rate to stay above 40fps constantly (and lowering graphic details ain't gonna help, as the limitation is with the CPU).

My i5 2500K overclocked to 4.5GHz would not bottleneck my 5850, and GPU usage would be at 99% at almost all time. My E5200 overclocked to 3.75GHz on the other hand would have the GPU usage on my 9800GTX+ struggle to reach 99% (mostly at around 60-90%), and frame rate will go up and down like a yo-yo between 15fps and 50fps. Being annoyed with that, I decided to try to push my overclock further, and finally managed to take my E5200 from 3.75GHz up to 4.25GHz- a 500MHz increase. With that I can finally see my GPU usage hitting 99% much more often, and my frame rate has increased to 20-60fps. But I still found the game not smooth due to the frame rate sharply jumping up and down between 20 and 60fps. So what I did was use the ingame frame rate limiter, I limited the frame rate to 30fps. Now the frame rate is only jumping between 20 and 30fps with only 10fps difference...and believe it or not, my eyes preception now find it to be smoother than having the frame rate jumping constantly between 20 and 60fps before. So I have now capped the frame rate at 30fps, and with plenty of GPU usage to spare, I can even turn up the graphic settings to max (but with shadow quality and texture at high instead of ultra)...and now the game is "smoother".

Normally, I would always deem 20-30fps unplayable...but unlike 1st and 3rd person shooter games that require you to have to aim and shoot at fast moving targets, games like GW2 actually ain't too bad.

So long story short...you should get the 7750 (around 10-15% faster than my 9800GTX+), and overclock your Q6600 to 2.8-3.0GHz if you can (GW2 would use up to 3 cores)...then you should be able to achieve similar results as my E5200 system on playing GW2. In the future when you got money to spare, upgrade your platform.

Hope this helps.

Nah, he has more than enough CPU power and RAM for Diablo III, it's a very modest game, it'll run on a potato with 2 electrodes stuck in it! The only tricky thing will be finding a graphics card that won't overload his power supply, and I'm really not sure what to advise there...

@OP, have you checked that you have a PCI-E slot to put the card in? And are there any spare power connectors on the PSU, or will you need one that doesn't need external power?

This.

Have you checked is your mobo compatible to run modern cards? It should be but double check just incase! You will DEFINITELY need a new PSU though.
 
I would think a 7750 should be ok...max power consumption 44W, and the Q6600 overclocked to around 3.0GHz should consume over 100W.

With that said, yes it would be a good idea to get a better PSU if the budget allows.

Thanks for that, interesting read. I have ordered the 7750, it comes on Monday.

I will have to look in to how to overclock as I have absolutely no idea, is there a link to somewhere I should read?

I haven't checked, don't know how to be honest. Hopefully it will be fine as i've already ordered it!

Will have to keep an eye on the PSU and if it does need upgraded maybe I can buy it somewhere locally so the wife never needs to know!

Don't worry. As far as I know socket 775 shouldn't come with older graphic slot like AGP...pretty sure it is a PCI-E x16 (and from the picture it doesn't look like a AGP slot, but PCI-E x16) :p

Fingers crossed. Big mistake if not! :eek:

I've been looking up how to change from the integrated to the new graphics card and have got a bit confused.

It seems the easiest way is to plug the monitor in to the new graphics card? Looking inside my PC i'm not sure how that will work as there isn't a hole in the case?

It is a bit difficult to imagine without the graphics card.

Is this the easiest way or is there another way to ensure the new graphics card is used?

Thanks for all your help :)
 
Yeah its a PCI-E 16x slot, not sure if it runs at 2.0 or 1.0 speeds.
Either way its fine for the card you've bought.

When fitting you just unscrew the tabs, take out two - your new card will fill the hole left.
Plug your monitor into the card, the computer should do the rest.
