Solved Which of these 2 ATI is better for my system?

[dorian hawkmoon]

Guys, I've heard 7750 is an awesome card...especially power requirement-wise. But I see there's a HD7770 almost at the same price!Which card would you suggest for my system (keeping in mind other components/PSU) that would be an better upgrade than my present gpu.

1) MSI GRAPHICS CARD HD 7770 1GB DDR5 (Stock/6-pin required)

2) SAPPHIRE GRAPHICS CARD HD 7750 1GB DDR5 OC (Factory OC/No 6-pin required...I think)

I have the Sapphire HD7770 installed in my system. I'm not sure what the difference between the two you list is.

I get a Windows Experience score of 7.5 for both video parameters.

Erm...HD 7750 is a much less power hungry card I've heard, in spite of the factory OC, whereas the stock 7770 draws more power - is it really better because of that? I wanted to go with the Oc'd HD7750...but as another option is available at the same price more or less, I want to make sure which one is better performance/power-wise

Hey dorian hawkmoon!
If you are looking for power, then 7770 is better. Regarding the PSU, as per AMD site you will need min 500W and for best performance, 600W power supply (or greater) with two 75W 6-pin PCI Express power connectors.
Now depends on you. If you want to buy new PSU as well with the card.

archer, those psu requirements are for total system specs, he should use a psu calculator to determine his needs.

I would go with the 7770

Just FYI, the 7770 only needs one 6r.

This should help also:

http://www.hwcompare.com/11880/radeon-hd-7750-vs-radeon-hd-7770/

Power wise 55w for 7750
80w for 7770

My 7950 is apparently a little piggy at 200w in comparison, does use 2 6r's.

I would go with the 7770 but you would need a psu calculator as stated from dude. But here is the comparsion for them. 7750 v 7770

 

[Faladu]

*cough* Benjy, u borrowed my compare.

I would go as high as your budget allows if you need a new PSU, the 7770 is of course better than the 7750, but not awesome, I wouldn't even refer to my 7950 that way. (OK, maybe 9 months ago when I first got it)

aka. I'd spring for a 7850 to get to 256-bit instead of 128-bit memory interface.

 

[benjy206]

*cough* Benjy, u borrowed my compare.

Yes I noticed we must have the same google fu

 

[dorian hawkmoon]

I can't buy another psu right now according to my budget! [it's 1 & 1/2 years old btw] My psu is listed in my specs.
eXtreme Power Supply Calculator suggests I have a 368 W min. and 418 W recommended(HD7770) and 316 W min. and 366 W recommended for HD7750 (in both cases Capacitor Aging is 30% as I use the PC a lot), a huge difference in power consumption! Provided 7770 price remains stable, you suggest I buy it?

 

[benjy206]

For sure

 

[Faladu]

I didn't realize you have a 6770 now?

The hwcompare between it and a 7770 would have me say it's not a big enough jump in performance.

In that case I would save a little more, shop at pcpartpicker.com and you'll know when you have enough for both PSU and Video, and then you won't regret it.... 7850 minimum for you for a reasonable jump.

benjy, nah I don't use google, I use dogpile.

Something like this combo:

Thanks guys for the research, much appreciated.

I understand that 7770 actually uses less power (80 W?) than 6770? Then it really is a good upgrade in that way also, seeing that it also lowers my power bills while upping the performance (even if by a small margin, I guess). I've been also hearing that the new HD 7xxx series uses a new technology that offers better power management and gaming power?

 

[Faladu]

Go as high as your budget allows OR not buy anything if thinking the 7770, since it is not a good jump for the cost, unless your 6770 is busted, I'd go higher....

Power wise I would ignore the increase in watts, unless your electricity per kilowatt is incredibly high, you probably won't even notice it.

.....still dragging your feet, eh?

Try this:

AMD Radeon HD 7790 Video Card Review w/ Gigabyte & Sapphire - Power Consumption - Legit Reviews

Looks like around 100w is what a typical 7790 will be when idle.

If you're a gamer and want performance, you have been warned to go 7850 or better! :devil: More than once!

 

[dorian hawkmoon]

Heh , nah it's okay.
It's a matter of cost-performance ratio mainly. Lemme see what the cards you suggested cost on the Indian market. If within my budget, I'll go for it. Or if not I have to opt for HD7770 (my r6770 is showing definite signs of age), as of now I'm in for investment in a Logitech G400 or suchlike, as my trusted old Abyssus is now deceased. Thank you for all the research and time .
