Nvidia graphics cards have recently become a lot like buses. You wait around for one for ages... then you're a little disappointed when it finally arrives and costs a lot more than you'd hoped.

We've been impressed by the overclocked AMP! cards from Zotac before - most recently the fantastic GTX 670 AMP! - and it's trying to continue that trend with the GTX 660 Ti AMP! edition.

Silence, they say, is golden. Personally I'm more concerned with gaming frame rates, but when something comes around offering zero dB sound levels and decent gaming speed, I'm going to sit up and take notice.

We were already pretty chuffed with the GTX 670 in its reference guise, but this factory-overclocked card is something special.

It's almost the same speed as a true GTX 570 and comes in cheaper. It's not quite as well designed a card as the Asus offering, but in price positioning it just makes a lot more sense.

The pinnacle of overclocked GTX 560s, but at what price?

The fastest single GPU card on the planet

Does this pricey GPU from Zotac stack up in price and performance?

So in the end we have a very fast card, as fast as AMD's own very fast card. But is there really a place for such a beast in the world today?

It's not necessarily that the GeForce GTX 550 Ti AMP! is actually a bad card, in many respects it's a perfect entry level gaming card. Unfortunately it simply doesn't make any sense in this market at that price. Drop the pricing closer to the £100 level and you have a card worthy of serious consideration. As it is though, you're better off grabbing a GeForce GTX 460 while you can.

If you're more of an Nvidia fan, or just love PhysX, and you're looking for the finest example of its mid-range Fermi silicon, then this Zotac GeForce GTX 560 Ti AMP! is quite simply the fastest you'll find.

The already blistering GF110 isn't noted for its overclocking headroom, and Zotac's AMP! Edition GTX580 offers noticeably – though not vastly – higher component-speeds than the stock GF110-based GTX580.

Another passively cooled graphics card but one that doesn't break the bank

Barely a month after Nvidia's last GF100 graphics card, the GTX 465, struggled out the stable door another new graphics card, the GTX 460 has turned up to steal its thunder.

If it's hard to justify the £300 price for a stock version of the card, though, is the 50MHz overclock Zotac has given its GTX 470 AMP! Edition worth an extra £70?

Is this Nvidia's Fermi finally done right?

Is Nvidia's GTX 470 an AMD Radeon HD 5870 beater?

Oh look, it's the 8800. Again

Water, water everywhere…

It's a measure of just how much AMD has caught up with NVIDIA that in order to spoil the launch of the new HD4890 the big green company brought forward the launch of its own new graphics card by over a week. In the old days of underperforming AMD GPUs it just wouldn't have bothered, now it feels the need to compete again.

Smaller may be better, but it's good to have a point too

The new 200-series cards from NVIDIA need to be good. The 9-series were very disappointing to say the least.And luckily for us, the GTX260 looks like it's pretty good
