Which of these is the best choice?

[pc 1]

Hello

Which of these 3 cards is the best choice, their prices are close, the lowest is 6770 and highest is gtx 550
i can only choose between those 3

SAPPHIRE HD 6770 1GB GDDR5

SAPPHIRE HD 7750 1GB GDDR5

Galaxy GeForce® GTX 550 Ti 1024MB GDDR5

The 6770 has the most power, but the 7750 USES the least amount of power, and is not that far off from the 6770. The 550Ti is not the greatest performer of the 3.

Well for starters the 6770 is a bit better than the 7750, it has around 50mhz more clock speed; but the best card you mentioned is the 550ti, although it also consumes more power, but it's like 10% faster than the 6770. My advise is, if you have a limited budget, go for the 550ti, if not try to get a cheap gtx 560 or even with a good deal the 560ti.

Of the three the 6770 will yield the highest results.

A lot misinformation here. The top card is the GTX 550ti. The 6770 then 7750 (800 Mhz).

@ pc 1: What kind of power supply do you have? Because there are performance differences between all these cards and all of these cards use different power.

The 7750 does not need the Power Supply connected to the card.

I noticed I posted about the 6670. A mistake noted from dudewitbow, I will change the post regarding the 6770.

A lot misinformation here. The top card is the GTX 550ti. Then the 7750, then the 6670.

The 7750 and the 6670 does not need the Power Supply connected to the cards.

lol, thanks for catching that

Will have to re-edit

so the choice should be between 6770 and 550ti, the difference in price between the 2 is $12
so should i get the 550ti?
regarding the psu i'm going to buy Thermaltake SMART M450W

Depends if you want to save money.

If not, then get the 550ti. The 450W will be able to supply enough power to the card and the rest of your system.

ofcourse i'd like to save money but if the performance difference between 6770 and 550ti is worth the $12 i don't have a problem in buying 550ti

 

[fantastik250]

The 550 Ti is the stronger card.

i also found asus gtx 550ti directcu, this is an overclocked card, do these cards die faster than the non overclocked ones?

 

[fantastik250]

No, the life of the card is dependent on the heat, so if the card is always running over over 85C then it will start to degrade over time. Of course keeping it as cool as possible will make the card last longer.
