We will be talking a look at the between level and inspecting the PowerColor PCS+ HD7850. The latest 7850 variation from PowerColor takes the reference design and tweaks it to be a better performer. This is due to the 140MHz overclock of the reference’s 860MHz Core Clock and the addition of the Memory being supercharger from 4800MHz to 4900MHz.

It will all come down to that last feature, one that no one else or very few will offer. In this case that feature will be the FleX option only from Sapphire. Just what is FleX? It’s being able to integrate at least three monitors to one GPU. We know just about all AMD cards can do that. But the fact is they can’t do it with having to go and purchase an expensive displayport monitor or buying an active displayport adapter which isn’t cheap either. With the FleX series you can do it without either. And that does for the card we will be looking at today, the FleX HD 7770 GHz Edition.

As of right now the Radeon HD 7750 maybe at the bottom of the performance chart but it does do well when it comes to moderate gaming and excel when it comes to digital video output and sound. Don’t let the placement of the card fool you. Sapphire’s newest 7750 have a nice advantage over the rest and it has nothing really to do with performance. The low profile HD 7750 is ideal for those that little space internally for larger cards. Yes, a great fit the many Dell and HP machine with the extra small enclosures and smaller power supplies.

One thing that all the different models, from all the different manufactures have one common is that in order to run AMD’s EyeFinity 3 feature you need to either include at least one monitor that has a DisplayPort capability, or are using some type of adapter to convert DisplayPort into the connection your monitor supports. At least that is the case except for the model we are about to touch on today, the Sapphire FleX HD 7950 3GB, which can run this Eyefinity with all the monitors being DVI. How about that for saving a few dollars? And at the moment, this is the fastest Radeon card that can do that.

Now, we get to the point of this review we are conducting today. Below the GTX 670, NVidia has not bought anything new to the market. While AMD has the 78xx sitting in that upper mainstream realm. As of right now the older GTX 560 and GTX 560 Ti 448 Cores covers that area for NVidia until they release the GTX 660. Yes, the GTX 560 Ti 448 Cores is a little aged but it definitely still holds its hold when it comes to gaming. There is no game on the market that you can say this card will not give you a delightful gaming experience.

Based on the Cape Verde XT chipset, the HD 7770 features 640 streaming processors and 1GHz of GDDR5 memory with a 128 bit bus looks to be in close competition of the older Radeon HD 6850 series. We will now put the card through its paces and see just how well it does.

That is when the new low profile Sapphire HD Radeon 6670 comes into play. This card is capable of playing back awesome video with the clearest of audio and at the same time can even game (well to a certain extent). But what most of you will like is what I mention in the first sentence of this paragraph, this card is a low profile single slot unit that can be placed in almost any rig.

If you were to take a look over at Sapphire’s website you will see several Radeon HD 6970 listed, 7 to be exact. Which, besides a possible bundled game, you may want to know what exactly the real differences between the models are. To put it briefly, all have a standard 880MHz core and 2GB of GDDR5 memory; some have a game bundle, some don't; but primarily it is a difference in the equipped cooler. That last one is where today's review sample comes in. It has dual fans to help with sound reduction, as well as better cooling in conjunction with the 8mm & 6mm heat pipes. There is also the dual BIOS switch, something normally available on many Radeon HD 6950 and HD 6990 models. We will get more into this during the review process, but felt we should break down what makes this model stand out.

The Radeon HD 6950 is from the Cayman Pro family that boasts an 800MHz core clock as well as 1250MHz GDDR5 memory clock. This along for many maybe enough to consider the card a worthy purchase but the 1408 shader processors and 2GB of memory definitely does help a lot.

Our sample we are testing today is from ASUS and you know they are not ones to leave reference numbers and parts alone. The Radeon HD 6950 DirectCU II increases the stock core clock to 810MHz while the memory clock remains the same. But where this Radeon HD 6950 is in the cooling department which is based on direct heat pipe technology to help keep core clocks are bay.

The Radeon HD 6750 from Sapphire specifications is identical to those of the reference design which would be a 700MHz core clock on 1150MHz memory clock. The unit has 716 million transistors, 36 texture units and 720 stream processors. With such specifications the unit should make for a pretty decent but lower end gaming machine.
