GTX 550ti or RADEON HD 6770

at a 150$ budget, you can get a HD 7770 or a HD 6850, the former being the most effecient power wise and will cause the least trouble to your psu, which you havent told us what your psu is.

you need more than 2GB RAM

Yup. 7770.

Thank you guys for your replies. but in the place I live the costs are a bit higher, I am from India and here 7770 costs about $190
My current PSU is 450W with 19Amps on the +12V Rail, please tell me whether it can handle the 7770 or I need to purchase a new PSU
I can purchase a GPU and PSU with an overall budget of $200.
I forgot to mention my motherboard is DG31PR, will the 7770 fit into this board?

Your PSU should be able to handle it and as long as your mobo has a PCIe slot, it will fit.

A choice between only those two, I'd try to get the 6770 as it's faster. Not faster enough that I'd buy it if it's more expensive. So basically get the cheaper of the two.

My MOBO has a PCIe 2.0 slot and 19 AMPS on +12V Rail are enough for the processor, MOBO and the GPU with hd 7770? Please reply

7770 will use around 8A, same for the OC'd CPU you have. This is 16A Already. You'll be pushing it assuming your PSU can really put out 19A.

I have no OC'd the CPU. All the components are running at their stock levels and I don't want to overclock because of the temperatures that I have in my place, I will be burning my PC down very soon if I overclock.

With my current setup, with all the components( DG31PR mobo, Dual Core E5300 CPU @ 2.6 Ghz and a 450W PSU which definitely gives +19A on the +12V rail (it is a trusted local brand)) If 7770 is better for my resolution and my specs, then will I be able to install a 7770 on the mobo and will my PSU be able to handle it? If not, kindly suggest me a good GPU for my specs and resolution in which I can play all the latest games. I do not want to max out every game that is out there, I just want the graphics to be clear and the game play to be smooth without any lag... Please suggest..

Your motherboard/processor won't be able to fully consume any of the video card's power. Not even the GTX 550 Ti. You'll probably need a new system for full use.

If neither of the two cards that I mentioned 550ti or 6770 will not be suitable for my current set up can you suggest me a good GPU for my build?

okay, just tell me what all games you play?

I would like to play all the latest games like crysis 2, battlefield 3, skryim etc.., and also upcoming games in the next 1 or 2 years. My resolution is going to remain the same 1280x1024. I have no plans for changing my build anytime soon...

oh! then go for the GTX 550 Ti if you're gonna run it at that resolution! take mine, I have an extra ZOTAC GTX 550 Ti 1GB DDR5 that I'm willing to sell.  

I thought you had an OC'd CPU. Must be thinking of wrong thread. 5200 is a 65W CPU? So thats (65/12) 5.xW. You are probably looking at around 16A. That's with the 7770, the GTX550TI will use more power.

I have a 5300 CPU that is a 65W (around 5A for it) and the mobo DG31PR, I don't know how much power it draws from the PSU, but assuming it draws around 5A, I'll be left with 9A for the GPU (7770). Will it be good enough for it? And will I be able to play the latest games at my resolution 1280x1024 at medium to med-high settings with this card?

I have a DG33FB, Core 2 Duo 2.33Ghz. it handles the GTX 550 Ti fairly well. Go get it.

You are suggesting a 550ti and I have also been suggested a 7770, but which one is better? Will my PSU be able to handle any of these cards? And one more thing, I know this question has been asked many times and still is unanswered, which one would be better AMD or NVIDIA. I have no personal preference, I just want the best performance out of my GPU on my rig.

I'd go for the GTX 550 Ti. Your PSU (Being 450w) will be able to handle it. I used to run my computer (250w) with the GTX 550 Ti. Worked well, but had random shutdowns after about 2 hours of gaming which is fine. 450, I don't think will be a problem.

Comparison -

I just have a reading of 19A on the +12V rail, but nvidia recommends a minimum of 24A on the 12V rail for the 550ti. So is it safe to run with my current configuration? You said that you were able to run it at 250W, can you tell me more about your system specs and the max output of your PSU at +12V rail?
And should I prefer nvidia over AMD for my resolution?

I don't know anything about my previous PSU, just know that it was 250w. It cheap as ***, about $30 or so. All I know is, it worked.

But yeah,
I recommend you get a nice PSU first  

(Sorry for DP.)

Just to be on the safer side, that is.

Any other suggestions apart from 550ti?? I heard that nvidia cards draw a lot of power and compared to a AMD give less performance.. please correct me if I am wrong.

7770 is faster then the GTX550TI. Between those cards I would get the 7770. Not only is it faster, but it uses less power and emits less heat. 7770 is better.

As mentioned the GTX550TI and 6770 are similar in performance. So buy the cheaper one.

Eh? The power consumption is SURELY better than the 550 but I don't think it's faster or anything. Only the Texel rate is better than the 550. Performance wise, 550 beats the 7770. For sure that is.

So you are suggesting that my PSU can handle both 550ti and 7770 and I should go for a 7770?

See, for the 550, buy a PSU to be on the safer side (But I think it's enough). Get the 7770 if you don't care much about performance (which is stupid).

If I was you, I'd definitely get the GTX550 Ti.

There are various flavors of 550ti (ASUS, Zotak, EVGA, MSI, FORSA, etc...), if I were to go with this one, which one should I pick?

I have the ZOTAC one. It's GREAT!

But I recommend you get the Asus, Gigabyte or the EVGA one.

ASUS : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Gigabyte : http://www.newegg.com/Product/Product.aspx?Item=N82E168...
EVGA : http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Asus should be the first priority.

Link? The 7770 is like a 6850, which is faster then the 550.

http://www.hwcompare.com/11894/geforce-gtx-550-ti-vs-ra...

comparing speeds like that isnt the best way to compare cards. cards speeds cannot be compared unless they are from the same family of gpus(you can compare a 6750 to a 6770 or a 6790, but not to a 6850 because its a different family of gpus)

an example would be 6950 vs 7850

stats wise the 6950 should win, but if you think a 6950 will beat the 7850, then that's a laughable matter, especially when overclocking gets put into the equation

I'm sorry, I didn't see any benchmarks in that link. Can you show me games where the GTX550TI beats the 7770?

Again, the 7770 performs like a 6850 most of the time. The 6850 is similar to the GTX460. The GTX550 is slower then the GTX460. Its rather impossible for the 7770 to be slower then the 550. Perhaps in an odd game here and there, but not overall.

i have the gtx 550ti and it handles games like a dream with tht res

Is there any other card that outperforms 550ti at 1280x1024 resolution?

Are you trying to troll us? We've been talking about one for quite some time now.

I am not trying to troll anyone.. I am just new to GPUs and I just wanted to make sure that I get the correct one for my specs.. If you think that I am trolling, then I em extremely sorry.. Instead of the two choices that I mentioned initially I was suggested a third one (the hd 7770) which made my decision even tougher. I was just trying to find out the best one for my rig.. I thought I would get some help when I post my queries here.. but I'm sorry if I have offended any one

I doubt you offended anyone, but you seem to be taking forever to decide what you want. And I thought you already ruled out the 7770 because it was too expensive where you live. 7770 if you can afford it, if not the cheaper of the 6770/GTX550.

By the way, the 5770 is identical to the 6770, so if they have a cheap one of those laying around feel free to buy it. Not trying to complicate matter here...

I recently tried both the HD 7770 and GTI 550 Ti in my build that has a 450 watt power supply (was using a dated GTS 8800 that failed). The HD 7770 had an odd issue where it would sometimes drop the signal to one or both of my monitors once the boot process got to the Windows 7 sign on screen. The problem would resolve by cycling the power on the monitor(s). I suspect it was simply a bad card. I also tried a GTI 550i (only 99.99 after rebate), it seems to be working fine, and I plan to keep it until I make a new build (probably sometime next year once I feel Windows 8 is stable enough). Note that according to the Windows 7 gaming graphics score my system produced the HD 7770 was slightly better than the GTI 550 Ti i.e. 7.5 vs. 7.3.

The end of the year is still months away so prices, rebates, available graphic cards, and relative performance can change (as drivers mature). While it is great to start researching now I would not make your final decision until you are ready to buy because things may have changed by then.

Hey 4745454b, one final question, I found some tools that measure the voltages of the PSU, I have attached the screenshots of the two tools that I found out, based on these readings, can you tell me if my PSU can handle a 7770? If it does then I will go for a 7770 or else I will go for a 550ti with a PSU upgrade..

Doesn't work that way.

Sorry but I didn't get you. Do you mean that the readings cannot be trusted? I just wanted to know if my PSU can support a 7770 or I need a PSU upgrade.

Meaning you can't look at a voltage reading and know what its output is capable of. If you look at something that's supposed to be 12V and its outputting 12.5v, what does that tell you about its total possible output? It doesn't. As I said, it doesn't work that way.

Again, not sure why you are dragging your feet. You said 7750 wasn't an option for you. Get a card already. Nothing new is coming.
