Playing DirectX 11 exclusive games?

[maxraj]

What is overclocking and what's the difference between overclocking CPU and GPU and how to do it? Does it cause any problem? I have a HD4650 currently and I can run any game upto now except the ones with the restriction of requiring only DirectX 11 version cards and that's the only barrier for me to play these exclusive games! For example, Ghosts, Crysis 3 etc. Will overclocking my graphics card help me run those games or will it just make games more smoother? Can I do anything to run DirectX 11 exclusive games on my HD4650? Anyhow, I am looking to save money to buy one R7 260X or HD 7770.

My PC configuration is
Motherboard: XFX X-G31
Processor: Core 2 Duo E7400 2.8GHz
RAM: 3GB (4GB Max)
Graphics: HD4650 (Approx. Total Memory 2300 MB)
PSU: Corsair VS450

Thank you.

no, HD 4650 will never run any directx 11 games.

Overclocking is to raise the clock rate of your CPU or GPU, thus getting more "horsepower" from them rendering you higher framerates, giving a smoother feeling in games.

To OC a CPU, it's always better to do it from the BIOS, as for the GPU you can use programs like MSi Afterburner or eVGA Precision.

Yes there's a risk into OC, if not done properly you could damage your components, but as long as you follow some of the many guides around the net (check the tutorials in tom's forums) you should be ok.

DX11 is a supported feature embedded on newer cards than your HD 4650 so it won't be able to run those games.

Thanks everyone. Now can anyone suggest me a decent gaming graphics card which could be ideal with a 450W PSU?

A point: DirectX is part of Windows and which version you can install depends on which version of Windows your system is running. If the OS is Vista, Win7 or Win 8 you can use DX11 (although it can be a pain to get onto Vista), but there is no way to get it onto XP, in fact XP can ONLY run DX 9 or lower.
There is plenty of overclocking guides out there, have a look over on the Overclocking Forum here at Toms, there's a good sticky on the subject of overclocking C2D chips.
Even with a good overclock the best choices for a card are a little limited, with the big DX11 titles demanding a full quad to give the best experience the CPU is going to be the main limiting factor.
Depending on budget the HD7750(DDR5)/GTX650 or HD7790/GTX650Ti would be my choices, they'll run off the existing power supply with no problems BTW, the power requirements are overstated to make up for all the cheap, nasty, low quality PSUs out there.
