The GTX 275 is a good card....if u are want to know if physx makes alot of difference to the visuals then the answer is yes and only if the game gets it right....for me, the one which made physx look better was batman: arkham asylum....it added so much tiny details in effects like papers flying when kicked, realistic fog, etc....Go for the GTX then....
physX makes no difference to graphic quality, its a physics engine.....hence physX, and its becoming obsolete as Nvidia and ATi wont agree on standardisation!!
Just look at Havok with geomod!!much better than physX and multi-platform!my honest recommendation would be to look at a dx11 gpu, like the 5850!
Tessellation is the future, and this is much better developed by DX11 gpu's, in game physics are beinf rendered on the cpu now, opposed to software controllers such as physX...like havok!!
Btw, havok is owned by Microsoft and supported by AMD (ATi) and Intel, where as physX is ONLY Nvidia, pushing thier prices up!!! price to performance ratio, the 5850 is your bag!!!if you can stretch to £200 and future proof yourself
If PhysX is importaint then go Nvidia but I'd say a GTX260 is plenty at that resolution.
Also consider the HD5770, it is well within budget and matches the GTX260 for performance while having DX11 available for future releases-but only if you use Vista or Win7, DX11 is not available for XP users.
Coozie hit it on the head, If you have XP you won't benefit from the dx11 capabilities of the HD 5770 but I do recommend it as an option for you as it will perform very well for your setup and later if you upgrade to Vista or Windows 7 (if you don't have it already) you will already be capable of running dx11.
If I were you and wanted to keep the cost down well below the 5850 I would go with the HD 5770.
I have a GTX 275 in my main gaming system but I would rather have the HD 5770 or crossfire for the extra features the 5770 brings to the table...
Every card has its pros and cons....ATi 5 series has DX11 but its for newer OS and the game r few right now....NVidia has Physx which adds special effects to ur game but costs a bit more than ATI.....But what ultimately will b the deciding points are Price, customer support and ur satisfaction....For ur res GTX 260 will do fine but if u want a more powerful card u can have 275....the ATi is also a nice option.....
i forgot to say i will be bulding a new pc in about 18 months to upgrade again as i7 will be dirt cheap, so i think that ill buy this gtx 260 its only £135 and by what ur all sayin it should hold its own in games at high settings at my res and it should cover me for the next 18 months.. and yes im still using XP http://www.overclockers.co.uk/showproduct.php?prodid=GX...
it does get to a point were the game can only do so well regardless of the cfx.
I have 2x HD 5770's in crossfire and my flat mate has the HD 5870
That is because they both are so over powered for today's games, neither can be used at its full potential. IF your upgrading in 18 months just get a single 4890 (equivalent to the 5770). i got a 4850 and it runs great.
@ Doggerdaz: The cards mentioned here are all fairly equal with the 1Gb HD4870 being slightly faster overall and the GTX260/HD5770 being slightly slower. At your given resolution the GTX275/HD4890 is simply going to be money wasted unless you are into >8X AA and 16X AF eye candy.
The final decision is yours: If PhysX is importaint then the slightly more expensive GTX260 is a good choice, if not the 1Gb HD4870 is a little faster and cheaper.
If you you planned to build new/upgrade sooner then I'd demand you get a HD5770 or even HD5850;). Yes, I know the DX10/11 goodness is not available for us low life XP users, but you could use the card in the new build, perhaps adding a second for CF in the process (my plan, Q1 2010).
And CRdloader: The HD5770 is just a little slower than the HD4870, the HD4890 is a fair bit faster than either.
As others stated, you are upgrading later so crossfire isn't an issue. A single HD 5770 and be done with it is my recommendation but to each his own. All 3 cards mentioned will do the current job just fine...
sorry, i thought you said you were looking to upgrade in 18 months, and my 5770 out performs a 4890!!!any way, its just an opinion at the end of the day man, the 260 is an ok mid range card, if your happy being milked by nvidia!lol jk jk
