So just to confirm, do I need to install additional fan systems to my PC? I see that these GPUs come with coolers...is that enough, or do I need to do something additional as well to cool down the overall system? If yes, how necessary is that?

The GPU fan is enough but you can just add a fan or two if you want it to run a bit cooler.

Minimumly use at least an intake fan and an exhaust fan.

If not those hot air not gonna ventilate well and trapped for a long time in your case.

a little cable management goes a long way.

you wouldn't need to worry about GPU though. even in my test above, the GPU was on burn in test, run it for a few minutes with high RPM fan on casing and such.

a typical user wouldn't even have to worry about the casing fan RPM and GPU temperature.

Hey guys sorry for bumping this again. Do I have any option of a GPU if I do not want to buy a new power source for it?

What's your old PSU?

We recommend at least a reliable PSU as those cheapo bundled PSU may not be reliable, and worst, may fail or even spoilt other components.

As for GPU recommendation that is low on power requirement, it sounds like the new GTX750/TI line, they are designe to be very efficient, and having a real low TDP or don't even need pcie 6pins connector. So by right, virtually all PSU should be enough to power it up.

Ok guys. My PSU is 300 watts.

To put in a GTX in there, do I need to upgrade or not?

Assuming I want a GTX650 TI Boost, what's my best course of action?

A quick look at the costs for the PSU will be good too.

Finally, do I need to take my desktop to the shops to get it fixed, or is a GPU/PSU easy to fix by myself?

I am also open to other cheaper GPUs even from AMD or anything else for a 300psu unit.

Ok guys I did my own research. It seems the best I can get is a GT640. Found a guy selling it cheap here on Lowyat. I play mostly 2D games so it should suffice for now.

According to Dell site, the PC supports GT640 with no additional PSU. Has been tested.

However, that version is 900mHz non-OC. The one I am getting is slightly OC to 940mHz. Is this effect on the power output minimal, or noticeable? Do you think I shouldn't get it as a result?

Depending on your budget, there's the GTX 750 now that uses very low power.

I just need answer to this: If you OC your GPU will it increase the TDP and watts required? By how much?

According to nVidia website, max TDP for the normal 900Mhz version is 65watts. But I see that the OC version by MSI also states 65watts for the TDP. Is this possible? The OC is 940Mhz.

As long as you overclock the power consumption is sure to increase. You won't feel any performance difference from 900 to 940 though.

Ok I understand. I know the performance increase is negligible.

But what about power consumption increase? Do you think it will also be negligible? Or still 65 watts TDP? Or maybe goes to 75 or 80 watts?

No, I don't think it goes that far.

No, as in it has no effect OR it has effect?

Sorry, more like YES it does increase.

NO as in it doesn't go that far in power consumption (eg reaching 75 - 80w)

You should wait and try and find the GT 750 / GTX 750 Ti, the reference design without external power connector. Nvidia made these cards so people with limited PSU power can use it.

GTX750 / 750 Ti is miles ahead from GT640. GT640 can be considered as outdated already.

I know, but it is around 3 times better than my GT620 in two separate benchmark scores I have seen. My GT620 is also actually fine enough for now for 2D games, and I rarely if ever play 3D games. Just want something that bit better.

I see. Do you experience lagging while playing 2D games? Because if I'm not mistaken upgrading the graphics card won't improve 2D games that much... It's mostly depends on CPU for 2D games.

If you are buying from Lowyat, GTX 650 Ti Boost is your best option. However NVIDIA are discontinuing the GTX 650 Ti Boost and replace with GTX 750 Ti. If you are not, you can consider Gainward GTX 660 2GB GS @ RM595 (Lingloong Garage Sales). Much more powerful, and also still being produced unlike the GTX 650 Ti Boost
