hi ,
hay i feel like you are looking to buy three of them..
forget i will provide you detail so you can enjoy much with more intense .

EVGA SuperSuper clocked GTX 260 55nm at 675MHz

Geforce GTX 260 with 216 Shaders and 55nm ,card runs at 675MHz, and although it could probably be overclocked even further.
The first impression is great. The card runs neck to neck with Geforce GTX 280 at reference speed which is impressive and the card is on average around 20 percent faster compared to the old reference clocked GTX 260 with 216 shaders at 65nm.

The card looks a bit more appealing and it works a bit better; below you'll find 3Dmark, World in Conflict and Far Cry 2 scores.

SuperSuper clocked 55nm GTX 260 is just one or two frames slower than GTX 280

In Far Cry 2 the new this is faster than GTX 280.the card is clocked much higher than the reference GTX 260, 65nm that works at 575MHz.

Sapphire Atomic HD 4870 X2

Sapphire has another surprise for those who always crave more.The card is HD 4870 X2 and The cooling is by Asetek.Sapphire also pounced on the chance to strap the card with cooling designed for cooling two RV770 cores. Apart from making sure that your cooling makes your graphics card live "long and prosperous" , you can also replace your CPU’s cooling and thus make the system even more stable.

HD 4870 X2 Atomic’s core runs at 800MHz with the memory running at 1000MHz.

Unlike some HD 4870 X2 cards, this card is single slot, but you should know that there are models of HD 4870 X2 cards that take up three slots.

GPU temperatures are around 65 degrees Celsius, which is a good result considering that the CPU block has to cool the quad core QX 9770 too.

PowerColor HD 4870 LCS is the fastest HD 4870 around

hi ,.
this is special one ,is liquid cooling is what you need then check this.
Powercolor is a company well known for non-reference ATI cardsThe card’s water block is specially manufactured for PowerColor HD 4870 by EK Water Blocks. The card is based on a non-reference PCB, with 4 phases in total - reference board has 3 phases in total.

HD 4870’s ticker is, as you all know, RV770 graphics processor, which is built in 55nm. It has 800 shader processors at its disposal, which is 2.5x more shader processors compared to the last generation - HD 3800. The same goes for texture units, and while HD 3800 had only 16, 4800 packs 40. AMD’s latest drivers come with Avivo converter that runs on HD 4800 and HD 4600 generation cards, so if you often find yourself converting video - you can put your card to good use.

Unlike reference HD 4870 at 750MHz for the GPU and 900MHz for the memory, Powercolor LCS HD 4870 is factory overclocked to 800MHz for the GPU and 950MHz for the memory.

Powercolor LCS HD 4870 is undoubtedly the fastest HD 4870 graphics card around, but it will probably be difficult to acquire.A simple overclock to 850MHz for the GPU and 1050MHz .water block does a great job and the card hits 30°C in idle mode and up to 45°C under a workload. This is a great result

MSI R4830 OC

AMD Radeon HD 4830 is a graphics card that fills the gap between HD 4850 and HD 4670 and if you take a look at the price-performance ratio, you'll clearly see that it's a good deal.

Compared to reference HD 4830 cards, R4830 has a couple of aces up its sleeve, such as 4+1 power phase and MSI’s dual-slot cooling. Better components result in less consumption and provide better overclocking, but that’s why R4830 cards end up being priced a bit higher than reference HD 4830s.Technical differences aside, HD 4850 and HD 4830 look very much alike. Reference design of both cards uses the same PCB and single-slot cooler, whereas MSI’s R4830 is a bit different and instantly recognizable.

The first thing you notice is a large aluminum cooler with a fan in the middle. The cooler is made of one piece of aluminum and it’s tall enough to make R4830 a dual-slot card.

The cooler touches the GPU, but not the memory, which is cooled by the fan. The card comes with 512MB of GDDR3 256-bit memory.

R4830 uses sturdy solid state chokes, solid capacitors and 4+1 phase power, which results in improved stability and consumption, as well as better overclocking. MSI overclocked the card by only 10MHz compared to reference 575MHz.

Just like Radeon HD 4870 and HD 4850, Radeon HD 4830 is based on RV770 core, manufactured in 55nm and packing 965 million transistors. Crippling the core to some extent is a usual practice in manufacturing of weaker models, and HD 4830 comes without 160 stream processors. This means it features 640 stream processors compared to full RV770’s 800 stream processors.

Since its performance is rated just below HD 4850 at 625MHz, AMD used lower clocks for HD 4830 cards. The GPU runs at 575MHz with the memory at 900MHz; note that HD 4850’s memory runs at 993MHz.

MSI R4830 card comes with the OC suffix, but 585 MHz is not something we’d consider as overclocked.For this graphics card, Catalyst Control Center allows maximum of 700MHz. Numbers in the GPU Clock field are the GPUZ readout after our overclocking.

For their Radeon cards, MSI makes a special version of CCC drivers (Catalyst Control Center), where you’ll find D.O.T. tool (Dynamic Overclocking Technology), and it enables hassle-free overclocking by simple choosing of already defined values. By choosing the “Commander” settings, we reached the R4830’s highest D.O.T.-allowed speed – 665MHz for the core and 1008MHz for the memory.
