Upgrade for ATI HD5770


I'm looking to upgrade my graphics card in my home desktop which I mainly use for gaming and general web use. My current setup is:

Mobo: Gigabyte P55A-UD3
CPU: i5 750 - 2.66Ghz
RAM: 8Gb 1600Mhz
PSU: Corsair HX 750W

It plays most games pretty smoothly but I'd really like to be able to ramp up the graphics on my 24" monitor - resolution of 1920x1080. Sometimes at this resolution in Skyrim and other games I notice some reduced fps at higher graphics settings.

Ideally I'd like to spend less than £150 if possible.

Should I get hold of another HD5770 and run them in crossfire - that would be a cheap option certainly - or should I just go for an all new card? Also, the rest of my hardware is getting a little old - will the CPU hold me back or is it OK still?

  1. I think it is not worth it to crossfire, because you may run to bigger Issue and If you can get a new card I don't see why you should crossfire it.

    This is what I'd get:

  2. i,d say to go with an hd 6870 because an hd 5770cf will not give that much of performance that an hd 6870 can give in other meaning waste of money.:)


    you can see there that an single hd 6870 is giving only 20% less performance then an hd 5850cf so think that an hd 5770 gives 15% less performance then an single hd 5850 so an hd 6870 will be more better buy.:)
  3. Awesome, thanks for the super fast replies!
    I've managed to find a HD6870 for £119:
    So unless there are any strong arguments to the contrary I'll probably be buying this when I get home this evening :)
    Cheers again
  4. I have a 6870 and I can only run it on High settings with 60fps.I recently had a 6870 crossfire and I was able to play it on Ultra but the drivers for this game are very bad so it barely made any difference.That being said stay away from crossfire for this game.

    Since £119 is still below your budget I suggest looking towards a GTX560ti or 6950.OR even better yet wait a month till AMD release's the rest of it's lineup.Prices may lower for the current cards.
  5. I would not buy the 5770 for crossfire or single 6870 if I were you. Games like Skyrim you are still going to have lag with a new 6870. - yes you do need a better gpu, but you also need to overclock your older cpu, it is quite capable when you give it a boost - http://www.tomshardware.com/reviews/core-i5-750-overclock,2438-12.html , I think you're money would be better spent on a cpu cooler now, then save for a couple months and get a more substantial gpu upgrade - ie, 6950, gtx 570, or a 7000 series. Upgrading from a 5770 to a 6870 is a waste of money in my opinion.
    Side note: I had a 6870, and skyrim lagged in some spots... I upgraded to a gtx580, skyrim lagged in a few spots... I overclocked cpu from 3.3ghz to 3.8ghz, haven't noticed any lag since then, all graphics settings maxed at 1920x1200.
  6. I've heard that Skyrim is CPU bound but it doesn't seem like it.
  7. I also have the i5-750 with a MSI 5770, my CPU running at 2.66 was hurting my FPS in Skyrim and BF3... overclocked to 3.0 and it helped my games run smoother. I also have an after-market CPU cooler... the Cooler Master Hyper 212 - AMAZING.... you can't overclock very well with the stock heatsink.

    I agree with NoodleToe... buy a $30 CPU cooler, overclock you CPU, and wait a bit for GPU prices to drop. Then grab a 6870 or 6950 (Depending on how much prices drop).
  8. I already have a CPU cooler - an Arctic Cooling Freezer 7 Pro - so I've given over-clocking a go and have got my CPU up to 3.5Ghz stable. Not had a chance to really test to see if it's made a big difference to the performance in Skyrim yet - if I'm still having problems I'll just deal with it for now and upgrade to a near top of the range graphics card in a few months.

    Cheers for all the advice!
  9. The ACF 7 Pro isn't really a good aftermarket heatsink.It's so small it can't really keep up with high demands for heat.

    Well I'm afraid I disagree with that statement - so far the temperature hasn't gone over 50C after several hours of playing Skyrim - considering I've overclocked the CPU from 2.6GhZ to 3.5Ghz I think that's pretty good.
  11. OK, you are fine with that. Good Luck :).
