Hi guys,

I've been wanting to upgrade my old geforce on my Dell Studio 540 on a £100 max budget and without having to change the psu as I'm not tech savvy! Thanks to a previous thread here and some advice i've finally narrowed down gfx card upgrade choice to a GTX650 or an R7250.

I've managed to get some photos together of my system below and I was hoping from this you'd be able to tell me for certain if either card will definitely work with my 350w psu and also which of the 2 cards you might recommend as the bettter one - my inclination is perhaps the R7250.

Sorry for the similarity of this thread to my previous, but just want to get thing's right before I buy!
Thankyou :)

My system specs are:
Intel Core 2 Quad Q9400 2.66 GHz 2.67 GHz
4 GB Ram
1TB HDD
NVIDIA Geforce 9800 512MB GDDR3 (PCI-E slot)

Thanks for the advice guys - If you think it'll work ok with my 350w psu it sounds like the HD7750 is definitely the best choice, so I've found what looks like a decent one here:-

However, as a wild idea and as i don't mind upping the budget a little bit, would a HD7770 also be realistic choice given my 350w psu?! I noticed a few older threads here where some poster also with dell 350w psu machine was after getting the 7770 and and the replies were that it would be perfectly viable for him, after assessing his pc and psu specs and using some of these online power calculators! Do you think it would be possible in my case also, or better to just stick with the 7750?!

Many thanks again :)

P.s - I'll be mostly looking to play SWTOR and WOW - preferably in good detail level on 23" monitor at 1920 res

I believe WoW favors nVidia, so the GTX650 may be stronger for that title. There are some versions (Asus has one) that do not need a PCIe power cable.
As to the power needed by a HD7750, a SBM build with one of those last summer pulled only 113W from the wall, so your PSU will be fine.

Thanks for the advice Onus :)

That's interesting about Wow and Nvidia. I've actually quit WoW at the moment and have taken up SWTOR so it shouldn't be too much of an issue for now unless i decide to return one day! That's great that the 7750 will run with the psu too - tho i'm guessing a 7770 would be pushing it too much!

I think the 7750 (unless the 7700 will run on my psu) will be the one i'll go for and i'll purchase this one from Scan i've seen here (i believe xfx is a good brand) :

Not being tech-savvy I've no idea of course how it will physically fit or install! I assume it will just slot into the PCI-E, though from the pics It looks a wider/thicker card than the old Geforce i have in there! I'm guessing the 2 leads going into my old gfx card are for power and will need to be plugged into the new card in the same spots also?!

The only thing that bothers me is i seem to have a thick blue cable that plugs into the board next to my old gfx card, that you can see from the pic i posted above, and i'm not sure if It will get in the way of the new thicker 7770 card?! Let's hope not!

Thanks :)

I have had mostly good results from XFX cards (all but a HD7970 I returned over defective fans). The HD7750 is short, and shouldn't block your SATA ports, even though it is wider. It will not need a power cable (the black/yellow on in your pic). I'm not sure what the little 2-pin blue/red cable is in your pic; a 2-pin would normally be the fan, but I don't see where that cable goes. If it is for HDMI from a sound card, you shouldn't need it with the new card.

Thanks for the advice - Sounds good news for the 7750! I must admit the new card does look shorter than the old so hopefully should be ok. Thats good it doesnt a power cable too. So in short, no cables at all! I believe my sound is integrated, i don't have a separate sound card on this pc, so i'm not sure what that smaller lead is! I'll just leave those two leads disconnected.

As a closing thought if i may ask, what's your view on the 7770? It's not a great deal more expensive so i thought it might be worth it. But will it be pushing it too much with the 350w psu?! In addition I believe unlike the 7750 it would need a power cable though, which it appears i do have! Though I'm not sure if the pin connector would be correct and also it appears physically to be a longer card too.

Thanks again for the advice, much appreciated :)
