Hello all,

I am looking to upgrade my current PC GPU for Gaming, and not sure what one. I was Considering the - Sapphire AMD Radeon HD 7870 XT 2GB GDDR5.

My Build is:

1)ASRock Z77 Extreme4 Socket 1155 VGA DVI HDMI 7.1 Channel audio ATX Motherboard

2)Corsair Vengeance 8GB (2x4GB) DDR3 1600Mhz CAS8 1.5V Non-ECC Unbuffered. 3)Intel Core i5 2500K 3.3GHz Socket 1155 6MB Cache

4)Sapphire RADEON HD 4870-1GB-GDDR5 SDRAM

5)Antec P190 Case

6)Windows 7 64 bit

I am only wanting to spend around £200

Many Thanks

Minimum PSU for the 7870 is 500 Watts. So I suggest your PSU should be 600 Watts minimum or over. You would have to open the case to see what Wattage your PSU is. Whenever you decide to upgrade a GPU card then always check the power the card requires and what the PSU output is and what connections the PSU has. Very important.

Within your £200 budget, just, you could get this: Nvidia GTX 770, which will easily outperform the Radeon HD 7870. It does have a greater power requirement though, Nvidia recommend 600W.

My PSU is a Corsair hx 650w

Check what connectors it has. Some higher end cards need two.

This power supply has 2 connectors for gpu, as they are needed for current card.

I was looking at the Radeon HD 7870 XT as it uses the Tahiti chip set which is said to be very good.

Do a comparison as I've neither the two cards. Check Mr Mistoffelees' recommendation.

GTX770 the way to go , slightly over your budget , but overclocked click here .

From personal experience I wouldn't go with an overclocked card. The 2-3 FPS boost you get is rather irrelevant for the extra price. Also some PC games have issues when using an overclocked GPU. Tombraider being the one that sticks in my mind, although there was another that I played, and had to under clock my GTX660 superclocked card with MSI after burner to play it.

I think you probably had a dodgy card there mrwoowoo , I have run my superclocked signature 680 for well over a year now , with no problems. Overclocking will also allow you to run at higher settings , and in general fps are between 5-10% better . If mrwoowoo's experiences were more widespread then I think we would of seen far more on the forums. Also it is not in manufacturer's intrests to suppy iffy gear . Good luck .

Thanks for advice all, I think I will go for the GTX 760 as that as my budget will allow, got to keep the wife happy :)
