This card comes in over-clocked at 880MHz (others 800-820MHz) right out of the box. It comes with an almost silent(stuck my finger in it to make sure it was running... OUCH!) over-sized fan(10cm), while all the other manufacturers settle for smaller ones. Temperatures run at 35C on idle to 54C under full load at 39% of max fan speed. So there's plenty of room there to overclock it even more and have sufficient cooling. It also has a great 3 year warranty unlike some others with only 2 years. My windows experience index went from 6.7 to 7.4 after removing my hd6670 2GB DDR3 card. It most definitely is the most powerful card on the market that needs no additional power from the power supply connector, running only from the PCI-Express slot in the motherboard. It's a great choice if you have a power-supply rated at 300W like I do knowing there's no need to upgrade to run this card. This card scores decent benchmarks and is able to cross-fire with no additional bridge connection thru software only and doubles it's performance being able to match or outdo nvidia gtx 560ti while barely sipping on power. Two of these are still cheaper than one gtx560ti. And the prices will only drop with time. So if you're on a budget and want a good performer all around, get this and have a peace of mind knowing that if you need to upgrade you can get another one of these and match cards that are now between $250-350(gtx560ti,hd6950). Since this card is brand new, the drivers for it will only improve with time making it an even better performer. It runs on the newest generation of DirectX 11.1, so the newest games will be supported with it. The most amazing thing I notice with this card is how much more vivid and sharper the colors are now while watching movies and playing games compared to my hd6670(connected to monitor with dvi-d cable). They really hit you in the eyeballs, giving you a very clear picture. I'm very happy with my purchase and I highly recommend it.

I wanted a graphic card that didn't need a 6/8 pin aux power. But I also wanted one that could game half way decent. This it it! I have built many machines for both myself and others with high-end cards, but this build was going to be a budget gaming PC re-build with a small PSU and a 3GHZ Phenom II X4 B75 processor. So I needed something wouldn't be a strain on the small PSU. This 55W DDR5 HD 7750 is amazing. I never thought it would be able to play Crysis 3 @ 1080p at medium settings, but it will! And Crysis 3 still looks great at medium settings. Sipping a measly 4.6 amps on the +12V rail, it leaves plenty of capacity for the rest of the system.

If you are stuck with a low end PC with a small PSU, get this card. You will be pleasantly surprised. And if you have a slim-line PC that requires a low profile card, look into the Sapphire HD 7750 low profile card. Just be sure you get one with GDDR5 VRAM, and not GDDR3.

I had high hopes for this card. I wanted to upgrade my MSI ATI R4670 to a better card with better performance without having spent too much. I don't play games, I do make and edit movies and clips, do little bit of graphic work and watch movies in all kinds of different formats including Blu-ray. So, I didn't want to go to a high end graphics card.

My criteria was a card with DVI, D-Sub and HDMI out-puts and not more than $120. This card had all my criteria. So, I ordered it and since I'm an Amazon Prime Member, care arrived in two days. I installed it in my computer, installed the latest driver and it was up and running. I ran the Windows Experience Index and it got a score of 7.5 for this card which was quit an improvement compared to the 5.6 score with my ATI R4670. But this was the end of good things.

First problem, all of my movies and clips would playback with issues like pixelating or freezing. I thought maybe I have codec issues. I installed updated codecs and all that but no help.

Second problem, this card will not playback Blu-ray movies no matter which type of out-put connection I used. I have two ViewSonic 24" LCDs. One is connected via DVI and the other one via D-Sub. I also have a 42" Vizio LCD TV connected to my rig via HDMI. No Blu-ray playback on any of them. So, I ran the Cyberlink's Blu-ray advisor and it turned a "Failed" result showing that the GPU does not support Blu-ray playback. Also, no DHCP support on any of the out-puts.

Next, I fresh installed a Windows and installed all the latest drivers for VGA and motherboard with latest BIOS and codecs. Still the same result. Tested on another rig and same result. Funny thing is that my MSI ATI R4670 on the same rig with same setup plays Blu-rays without any issues.

I purchased this card as an upgrade to an aging 5670, which before this card was released, was the best GPU you could buy without additional power from the PSU. This card doesn't dissapoint, my 3dmark03 score went from 27,000ish with the 5670 to a nicer 60,000ish score with the 7750 (at 960/1265, factory is 880/1125). The fan at 100% is very quiet, IMHO, so to keep the card as cool as possible, I leave the fan at that speed. The heat sink/fan combo make this card even better as on my 5670 the ram had no heat sinking while this one has the processor and ram under the fan and under a heat sink, perhaps aiding in the better than average OC (for 7750's). The toughest game I have at the moment is GRID, however, it'll run it at 1080P/Ultra/8xAFAA like butter on a 32'' LCD. If you want a nice mid-range card that doesn't require external power, this is the one to get.

Other System Specs:
AMD Phenom II X4 945
8 Gigs of Ram
1TB WD Green HD
7750 Gigabyte (960/1265)
