6750 vs 6770 vs GTS 450

Processor: Intel E5700 3.0 Ghz Dual Core (Might Overclock upto 3.3Ghz)

MOBO: Asus P5G41T-M LX (PCIEx16 1.1v, i am guessing)

RAM: 4 GB 1333Mhz Transcend


I initially planned on getting the 6750 or the 6770 which came within my range. But people recommended that the mobo and processor would bottleneck the graphics card. So then I decided on the 6670. The same people said that as the 6670 was a PCIE 2.1 card, it would create problems with my mobo. Then I decided on the GTS450 (which i believe is similar to the performance of 6750?). Now the other people said that the 6750 was better than the GTS450 and that the 6750 was completely backward compatible with my mobo.

Now I am confused between them and i thought it would be better to get a more professional opinion from this forum.

6670 - 5900 rupees (118 US$)
6750 - 6400 rupees (127 US$)
6770 - 7200 rupees (143 US$)
GTS450 - 6300 rupees (126 US$)


Thanks


PS: I have a Corsair CX430 V2 PSU.

PPS: I don't have money to get a better card.

Get the 6770 It is by far teh strongest graphics card out of those and ur cpu bottleneck will only be in few games.

Do you live in India?

Anyway, the 6770 is the best among those cards that you speak of. However, while PCIe Standards are usually backwards compatible, v2.1 may (or may not) cause issues with v1.x mobos,, so you're better off using a card like the 550 Ti, which performs similar to or better than the 6770 and uses the version 2.0 of the PCIE standard. However, as far as i know you'll find that card for around Rs.8k (again i'm assuming you're in India).

However, see if you can find a 5770, since it's 98% as fast as the 6770. Since it's older, therefore there's a strong chance that you'll find one that uses PCIE v2.0.

I recommend a GTS 450, it holds its weight i all games i have played. I can can play every game set to medium specs and play no problem with it. Its a good price for the card to. i got my when it first came out for about 200$

Hey i've just been looking at cards made by Sapphire. They seem to be using PCIE v2.0, which means they'll work fine.

Here are a few links to a Delhi-based website:

Look around for better deals, the 5770 was Rs.6800 back in May, though since the rupee's nosedived i don't know if you'll find similar prices.

Anyway, go with the 6770 (from Sapphire). What resolution does your monitor use? At 1366x768, the 6770 is ample.

BTW, Sapphire's site confirms it's a PCIE 2.0 card: http://www.sapphiretech.com/presentation/product/?cid=1...

i have a board having pcie x16 v 1.0, and a hd 6770 and no issue (there is 0.01 percent of chances of compatability issue)

your cpu is bottleneck (a little) for 6770, but 6770 provide great bang for buck

I agree with the 6770. It is going to fit you the best.

Ok.. I guess i'll go with the 6770. I was mostly worried about my mobo supporting it. The CPU bottle neck was secondary. I guess if the bottleneck isn't that much. I'll go with the 6770. Thanks guys!


@ojas

Yes i am from india. Chennai specifically. My monitor's resolution is 1366x768 as you have mentioned. The 550 Ti becomes too expensive for me. I am considering getting an MSI 6770. Costs 7200 but there is a lot of scope to reduce it down to 6800 through bargaining.

Is the difference between them significant engough?
MB:16%
TR:44%

seem significant enough.
